    Question:6

    What is commensalism?

    Answer:

    Relationship between two organisms in which one organism is benefitted, and there is a neutral effect on another organism; is called commensalism.
    Many commensals live in the alimentary canal of humans to get shelter and food, but they have neither a positive nor negative impact on humans.

    Question:8

    What is Mycorrhiza?

    Answer:

    Mycorrhiza is a mutualistic association between the fungus and the roots of higher plants. The fungi get shelter and food, and lieu of that helps the plant in absorption of phosphorous from the soil. It also provides resistance to the pant from root-borne pathogens.

    Question:10

    Why do high altitude areas have brighter sunlight and lower temperatures as compared to the plains?

    Answer:

    When sunlight reaches us, it undergoes refraction through several layers of the atmosphere. The relative degree of refraction at higher altitude is less than at lower altitude. Due to this, sunlight appears brighter at high altitudes than in plains. Temperature reduces with increase in altitude. Due to this, higher altitudes have a lower temperature compared to the plains.

    Question:11

    What is homeostasis?

    Answer:

    The process by which an organism maintains constancy in its internal environment is called homeostasis. Osmoregulation and thermoregulation are parts of homeostasis.

    Question:12

    Define aestivation.

    Answer:

    When an organism goes into summer sleep to avoid unfavourable environment; this process is called aestivation.

    Question:13

    What are diapause and its significance?

    Answer:

    The period of suspended development in order to tide over the unfavourable conditions is called diapause.

    Question:14

    What would be the growth rate pattern, when the resources are unlimited?

    Answer:

    When resources are unlimited, the growth rate of population is exponential. This gives a J- shaped curve on the graph.

    Question:15

    What are the organisms that feed on plant sap and other plant parts called?

    Answer:

    Organisms that feed on plant sap and other plant parts are called phytophagous.

    Question:16

    Answer:

    A range of symptoms due to the low atmospheric pressure of high altitudes, the body does not get enough oxygen is called high altitude sickness. The symptoms of altitude sickness are nausea, fatigue and heart palpitations.

    Question:17

    Give a suitable example for commensalism.

    Answer:

    Egrets ride on the back of cattle. When cattle forage for grass, insects fly away abruptly. This gives the egrets a chance to feed on those insects. In this relationship, cattle get no benefit from egrets. This can be considered a suitable example of commensalism.

    Question:18

    Define ectoparasite and endoparasite and give suitable examples.

    Answer:

    Ectoparasite: Parasites which live on the body of hosts are called ectoparasites, e.g. leech and ticks.
    Endoparasites: Parasites which live inside the body of hosts are called endoparasites, e.g. roundworms and hookworms.

    Question:19

    What is brood parasitism? Explain with the help of an example.

    Answer:

    In this type of parasitism, a bird lays its eggs in the nest of another bird. The eggs resemble those of the host bird. The host bird incubates the eggs, unaware of its actual identity. This is seen in Koyal (cuckoo) which lays its eggs in a crow’s nest.

    Short Answer Type Questions:

    Question:1

    Why are coral reefs not found in the regions from West Bengal to Andhra Pradesh but are found in Tamil Nadu and on the east coast of India?

    Answer:

    In West Bengal and Andhra Pradesh, freshwater is released from the Ganges and some other rivers. Due to this, coral reefs are not found in regions from West Bengal to Andhra Pradesh. From Tamil Nadu to the southern tip of the east coast, coral reefs are present because of no interference from freshwater.

    Question:2

    If a freshwater fish is placed in an aquarium containing seawater, will the fish be able to survive? Explain giving reasons.

    Answer:

    Freshwater is adapted to maintain its homeostasis in freshwater. It is unable to do so in saline water. Hence, the fish will not survive in an aquarium, which contains seawater.

    Question:3

    Why do all the freshwater organisms have contractile vacuoles whereas the majority of marine organisms lack them?

    Answer:

    In freshwater organisms, the concentration of solute inside the cell is higher than that in the external environment. This means that the external environment is hypotonic. This leads to a movement of water inside the cells because of osmosis. Contractile vacuoles work like safety devices and prevent lysis of the cell. In marine organisms, the concentration of solute inside the cell is lower than that in the external environment.
    This means that the external environment is hypertonic. Hence, the cell does not have to face the risk of lysis. This explains the absence of contractile vacuoles in marine organisms.

    Question:4

    Define heliophytes and sciophytes. Name a plant from your locality that is either heliophyte or sciophyte.

    Answer:

    Heliophyte: Plants, which are adapted to live under plenty of sunlight, are called heliophytes, e.g. banyan. Heliophytes form the roof of a forest.
    Sciophyte: Plants, which are adapted to live under low light conditions, are called sciophtyes, e.g. herbs. Sciophytes form the understory of a forest.

    Question:5

    Why do submerged plants receive weaker illumination than exposed floating plants in a lake?

    Answer:

    Most of the colours from the visible spectrum fail to reach deep into a water body. This happens because of the refraction of light through different layers of water. Due to this, floating plants get plenty of sunlight, but submerged plants get weaker illumination.

    Question:6

    In a seashore, the benthic animals live in sandy, muddy, and rocky substrata and accordingly developed the following adaptations.
    a. Burrowing
    b. Building cubes
    c. Holdfasts / peduncle
    Find suitable substratum against each adaptation.

    Answer:

    (a) These animals live in the sandy substratum and make burrows, e.g. lobsters, crabs, etc. (b) These animals live in muddy substratum as cube-like aggregates. The small size of cube helps in passive feeding mechanisms, e.g. zooplanktons.
    (c) These animals live in the rocky substratum and attach to the substratum with the help of holdfast, e.g. sponges.

    Question:11

    In an association of two animal species, one is a termite which feeds on wood and the other is a protozoan Trichonympha present in the gut of the termite. What type of association do they establish?

    Answer:

    Termite and Trichonympha show mutualism; a relationship in which both the organisms are benefited from each other. Trichonympha breaks down cellulose in the wood and thus help the termite in the digestion of wood. Trichonympha also feeds on fragments of wood.

    Question:12

    Lianas are vascular plants rooted in the ground and maintain erectness of their stem by making use of other trees for support. They do not maintain a direct relationship with those trees. Discuss the type of association the lianas have with the trees.

    Answer:

    Lianas are in competition with other trees. While taking support from other trees, lianas usually strangulate the other tree. They also compete for sunlight and water and in the process, harm the host tree.

    Question:14

    What is a tree line?

    Answer:

    The edge of the habitat at which trees are capable of growing is called the tree line. Trees show stunted growth at the tree line. They cannot grow beyond the tree line because of unfavourable environmental conditions.
    Treeline shows a gradual transition from dense cover to sparse cover.

    Question:15

    Long Answer Type Questions:

    Question:1

    Comment on the following figures: 1, 2 and 3:


    Answer:

    Figure 1 shows a population of species A. All the individuals are interacting among themselves.
    Figure 2 shows a community with three populations of A, B and C. They are interacting with each other and their environment.
    Figure 3 shows a biome with three communities. One of the communities is in the climax, and the other two are at different stages of development. All the three communities are in the same environment, and they interact with each other and with the environment.

    Question:2

    An individual and population have certain characteristics. Name these attributes with definitions.

    Answer:

    A population has certain characteristics that and individual does not have. Following are the main attributes of the population:

    1. Birth Rate: An individual is born, but a population shows the birth rate. The birth rate is usually expressed in terms of the number of births per thousand population.

    2. Death Rate: An individual dies, but a population shows the death rate. The death rate is usually expressed in terms of a number of deaths per thousand population.

    3. Sex Ratio: An individual is either a male or a female, but a population shows sex ratio. The ratio of a number of males to the number of females is called sex ratio. For example, the sex ratio in India is 934 females to 1000 males.

    4. Age Distribution: An individual can be of a certain age, but a population has people of different ages. For convenience, age groups are taken into consideration. Age group is normally categorized as pre-reproduction, reproduction, and post-reproduction age groups.

    5. Population Density: Population density is usually taken in terms of the number of individuals per square km. Population density depends on various abiotic factors. The plains usually have extremely high population density while mountains have very low population density.

    Question:3

    The following diagrams are the age pyramids of different populations. Comment on the status of these populations.

    Answer:

    Figure A shows a population, in which the ratio of individuals in pre-reproductive age is highest, following by reproductive age and post-reproductive age. This pyramid shows a growing population.
    Figure B shows a population in which the number of individuals in pre-reproductive and reproductive age is equal. A number of individuals in post-reproductive age is less. This pyramid shows a stable population, i.e. population growth, is negligible.
    Figure C shows a population in which the number of individuals in pre-reproductive age is the least. The number of individuals in reproductive age is the highest. Less number of individuals in pre-reproductive age shows a negative growth rate in the population. This pyramid shows a population in de-growth.

    Question:4

    Comment on the growth curve given below.

    Answer:

    The growth curve in this figure shows logistic growth of population. We know that resources are limited in nature, and they cannot support unlimited growth in population. Limited resources mean tough competition for resources among individuals. Only those survive which are fit to survive in such a condition. This is what happens in a real-life situation.
    In the initial phase, the population shows a lag phase, i.e. it grows at a slow pace.
    The lag phase is followed by a phase of acceleration, during which population growth is rapid. The acceleration phase is followed by a phase of deceleration, during which population growth slows down.
    Finally, a phase comes when population density reaches the carrying capacity. Carrying capacity defines the load limit of nature; in terms of sustaining a particular population density. Once the population density reaches the carrying capacity, it reaches the phase of the asymptote. This is the phase when population beings to show negative growth.

    Question:5

    A population of Paramoecium caudatum was grown in a culture medium. After 5 days, the culture medium became overcrowded with Paramoeium and had depleted nutrients. What will happen to the population and what type of growth curve will the population attain? Draw the growth curve.

    Answer:

    The population of Paramoecium will show logistic growth which can be shown by a sigmoid curve. The population growth will show the following phases:
    (a) Lag phase
    (b) Acceleration phase
    (c) Deceleration phase
    (d) Asymptote phase
    The asymptote phase shall be reached on the fifth day. The following figure shows the growth curve:

    Question:6

    Discuss the various types of positive interactions between species.

    Answer:

    Following are the positive interactions between species:
    (a) Mutualism: This is a relationship between two organisms in which both the organisms are benefitted. Lichen is a particularly good example of mutualism. Lichen is an association of fungi and algae. The fungal part attaches to the substratum and gets water and minerals for the algal part. The algal part carries out photosynthesis and provides food to the fungal part.
    (b) Commensalism: This is a relationship between two organisms in which one organism is benefitted, while another organism is neither a gain nor a loss. Egrets keep on sitting on the back of herbivore animals, like buffalo, cow, etc. when the cattle forage for grass, the insects under the grass fly away haphazardly. This gives a chance to the egrets to feed on insects. Without the help of cattle, it will be difficult for egrets to find insects in the grass. In this relationship, there is no benefit to the cattle.

    Question:7

    In an aquarium, two herbivorous species of fish are living together and feeding on phytoplankton. As per the Gause’s Principle, one of the species is to be eliminated in due course of time, but both are surviving well in the aquarium. Give possible reasons.

    Answer:

    Gause proposed that when resources are limited then out of the two competing species, one of the species will eventually become extinct. The species with superior predatory skills will survive in the end. But the evidence for such conclusive extinction is rare in nature. Many recent studies do not support Gause’s Principle of competitive exclusion. One of the means to survive is called resource partitioning.
    For example, if two species compete for the same resource; they partition their time of foraging or different foraging patterns. MacArthur showed that five species of warblers living on the same tree effectively change their feeding patterns to survive in limited resources. The same thing can happen in the given aquarium. Either the resources are unlimited, or two herbivorous species of fish may have changed their feeding times or feeding pattern to survive in the aquarium.

    Question:8

    While living in and on the host species, the animal parasite has evolved certain adaptations. Describe these adaptations with examples.

    Answer:

    Parasites show the following types of adaptations:
    (a) Morphological Adaptations: Many parasites are bigger in size than their free-living counterparts are. This helps in producing more eggs, necessary for survival. Endoparasites lose unnecessary sense organs to conserve resources. Endoparasites lose their gut or gut is reduced in size. They absorb nutrients through the skin. Special organs for attachment are present, e.g. suckers.
    (b) Life Cycle Adaptations: An endoparasite needs some way to enter another host. Many parasites use a secondary host for this purpose. For example, plasmodium uses mosquitoes as secondary hosts so that they can easily infect another primary host. Some parasites lay their eggs in the lower portion of the alimentary canal of the host so that eggs or cysts can go out along with stool. Later on, the cysts get transmitted to another host through contaminated food and water, e.g. Entamoeba histolytica.
    (c) Immunological Adaptations: Some parasites engulf antigens from the host. Some parasites disturb the immunological function of the host. These mechanisms help the parasite survive immunological response of the host.
    (d) Biochemical Adaptations: Many endoparasites do not produce digestive enzymes. They rely on the host’s digestive enzymes and absorb the simple nutrients. Endoparasites do not carry out the synthetic reaction. This is possible because their energy need is very low, which is fulfilled from the host’s resources.

    Question:9

    Do you agree that regional and local variations exist within each biome? Substantiate your answer with suitable example.

    Answer:

    A biome is a climatically and geographically contiguous area with similar climatic conditions. Both organic and inorganic components are similar in a particular type of biome. However, regional and local variations exist within each biome. To understand this, let us consider the following examples.
    Coniferous forest is a type of biome which mainly contains trees which bear cones with sees inside. In all the coniferous forests around the world, coniferous trees are the main plant species. But regional variations exist in coniferous forests. The coniferous forests of North America are dominated by black spruce. On the other hand, the coniferous forests of northeast Europe are dominated by Norway spruce. Forests of Siberia are dominated by pine. This shows regional variations in a particular type of biome.
    In the case of coniferous forests, the canopy is so thick that negligible sunlight reaches the ground. This results in sparse vegetation on the ground. The dense canopy on top and sparse vegetation at ground show local variations in a particular type of biome.

    Question:10

    Which element is responsible for causing soil salinity? At what concentration does the soil become saline?

    Answer:

    Minerals are responsible for causing soil salinity. Following are some of the cause for the increase in soil salinity:
    High level of salt in the soil.
    Water table movement because of landscape features.
    Human activities; like clearing of land and excess use of synthetic fertilizers.
    Salt runoff from streets can happen in cold climates because salt is applied on the road to prevent snow accumulation.
    Measurement of Soil salinity: Soil salinity is measured in terms of a gram per litre of soil solution or electrical conductivity in dS/m. Soil salinity is usually determined from an extract of the saturated paste of soil, and then EC is termed as ECe. When 4 < ECe < 8, the soil is termed as slightly saline. When 8 < ECe < 16, the soil is termed as moderately saline. When ECe > 16, the soil is termed as highly saline.

    Question:11

    Does light factor affect the distribution of organisms? Write a brief note giving suitable examples of either plants or animals.

    Answer:

    Light is an important factor in determining the distribution of organisms. We know that green plants need sunlight to carry out photosynthesis, and hence the distribution of green plants is highly dependent on the amount of illumination. This is the reason; tropics have dense plant cover, but poles have negligible plants. Moreover, plants also need sunlight for flowering. This phenomenon is called photoperiodism.
    Hence, based on photoperiodism, plants are categorized as short-day plants, long-day plants and day-neutral plants. The area near equator gets a long duration of light as compared to the area near poles. Thus, this affects the distribution of plants on earth. Animals too depend on light and show certain behavioural pattern based on diurnal and seasonal variations in light. Many animals get up early in the morning and start foraging. The nocturnal animals remain active during the night only, e.g. owl. Reproductive and migratory activities are also governed by the amount period of illumination in many animals.

    Question:12

    Give one example for each of the following:
    i. Eurythermal plant species _______________
    ii. A hot water spring organism _______________
    iii. An organism seen in deep ocean trenches _______________
    iv. An organism seen in compost pit _______________

    vii. Soil organism _______________
    viii. A benthic animal _______________
    ix. Antifreeze compound seen in antarctic fish _______________
    x. An organism which can conform _______________

    Answer:

    (a) Gracilaria (b) Alycyclobacillus (c) Giant tube worms (d) Earthworm (e) Misteltoe (f) Pine (g) Earthworm (h) Sponge (i) Antifreeze glycoproteins (j) Mangifera

    Have a question related to CBSE Class 12th ?

    hello,

    Yes you can appear for the compartment paper again since CBSE gives three chances to a candidate to clear his/her exams so you still have two more attempts. However, you can appear for your improvement paper for all subjects but you cannot appear for the ones in which you have failed.

    I hope this was helpful!

    Good Luck

    Hello dear,

    If you was not able to clear 1st compartment and now you giving second compartment so YES, you can go for your improvement exam next year but if a student receives an improvement, they are given the opportunity to retake the boards as a private candidate the following year, but there are some requirements. First, the student must pass all of their subjects; if they received a compartment in any subject, they must then pass the compartment exam before being eligible for the improvement.


    As you can registered yourself as private candidate for giving your improvement exam of 12 standard CBSE(Central Board of Secondary Education).For that you have to wait for a whole year which is bit difficult for you.


    Positive side of waiting for whole year is you have a whole year to preparing yourself for your examination. You have no distraction or something which may causes your failure in the exams. In whole year you have to stay focused on your 12 standard examination for doing well in it. By this you get a highest marks as a comparison of others.


    Believe in Yourself! You can make anything happen


    All the very best.
