NCERT solutions for Organisms and Populations Class 12 are given below:

Organism and Population Exercise:

Q 1. How is diapause different from hibernation?

Answer:

Many insects and other invertebrates go through a period of suspended growth or development known as diapause, during which their metabolic activities are drastically reduced. On the other hand, hibernation is a sleep-like state that some animals, like fish and amphibians, use to get through the winter months in order to survive the cold and lack of food.

Organisms and Populations Class 12 NCERT Solutions

Q2. If a marine fish is placed in a freshwater aquarium, will the fish be able to survive? Why or why not?

Answer:

Marine water fishes will not be able to survive in fresh water because marine water fishes are adapted to live in salt water conditions. If they are shifted to freshwater, the process of osmoregulation in them will be affected. Due to the internal high salt condition in fish, the freshwater will come inside the body of fish causing fishes to swell up, ultimately bursting.

Organisms and Populations Class 12 Solutions

Q3. Most living organisms cannot survive at temperature above 45ºC. How are some microbes able to live in habitats with temperatures exceeding 100ºC?

Answer:

Some microbes can survive in temperatures as high as 100^{^{o}}C because these microbes are adapted to live at high temperatures. These organisms contain enzymes which can work at high temperature. This is why they can be found at thermal vents, hot springs etc. The organisms which are unable to survive high temperatures have enzymes that gats deactivated at high temperatures.

Organisms and Populations Class 12 Solutions:

Q4. List the attributes that populations possess but not individuals possess.

Answer:

The term population refers to a group of individuals of any species living in a well-defined geographical area, sharing or competing for similar kind of resources and potentially interbreed.

Population Attributes: A population has certain attributes that an individual organism does not have. For example, individuals may have births and deaths, but a population has birth rates and death rates. The various population attributes are as follows:

1. Birth rate (natality)- It is the ratio of live births in an area to the population of an area. It is expressed as the number of individuals added to the population.

2. Death rate(mortality)- It refers to the live deaths in an area to the population of an area. It is expressed as the number of individuals removes from the population.

3. Sex ratio- It is the ratio of the number of male or female individuals per 1000 individuals.

4. Age distribution- A population at a given time is composed of different individuals belonging to different age groups. If the age distribution is plotted for the population, the resulting structure is called age pyramids. The shape of pyramids reflects the growth status of the population.

5. Population density- The number of individuals of a population present per unit area at a given time.

Organisms and Populations Class 12 NCERT Solutions:

Q5. If a population growing exponentially double in size in 3 years, what is the intrinsic rate of increase (r) of the population?

Answer:

t = log^{2}r or r = log^{2}t = 0.7931/3 = 0.264

Thus, if a population growing exponentially double in size in 3 years, the intrinsic rate of increase (r) of the population will be 0.264.

Organism and Population Class 12 NCERT Solution:

Q7. An orchid plant is growing on the branch of mango tree. How do you describe this interaction between the orchid and the mango tree?

Answer:

An orchid that grows on mango tree represents an interaction called commensalism. In this type of interaction, one species is benefitted while another one remains unaffected. Orchid acts as an epiphyte on the mango tree as it does not derive nutrition from it but uses it for support while mango tree remains unaffected.

Class 12 Biology Chapter 13 Question Answer:

Q10. Write a short note on

(a) Adaptations of desert plants and animal

Answer:

Plants found in deserts are well adapted to overcome the harsh desert conditions such as water scarcity and scorching heat. Adaptations of desert plants include

1. To reach to underground water, plants have an extensive root system.

2. They bear thick cuticles and sunken stomata on the surface of their leaves to reduce transpiration.

3. In Opuntia, the leaves are entirely modified into spines and photosynthesis is carried out by green stems.

4. A special pathway that is C4 pathway is found to synthesize food. It enables the stomata to remain closed during the day to reduce the loss of water through transpiration.

Animals found in deserts such as desert kangaroo rats, lizards, snakes, etc. are well adapted to their habitat. The kangaroo rat found in the deserts of Arizona never drinks water in its life. It has the ability to concentrate its urine to conserve water.

(b) Adaptations of plants to water scarcity

Answer:

Plants found in desserts are well adapted to cope with water scarcity and scorching heat of the desert. Some of these adaptations are as follows:

1. Plants have an extensive root system to tap underground water.

2. They bear thick cuticles and sunken stomata on the surface of their leaves to reduce transpiration.

3. In Opuntia, the leaves are modified into spines and the process of photosynthesis is carried out by green stems.

4. Desert plants have special pathways to synthesize food, called CAM (C4 pathway). It enables their stomata to remain closed during the day to reduce water loss by transpiration.

Class 12 Biology Chapter 13 NCERT Solutions:

(c) Behavioural adaptations in animals

Answer:

Various organisms are affected by various environmental conditions. To overcome these environmental conditions, organisms undergo adaptations such as migration, hibernation, aestivation, etc. The adaptations in the behaviour of an organism are called behavioural adaptations. For example, ectothermic animals and certain endotherms exhibit behavioural adaptations. Ectotherms are cold-blooded animals such as fish, amphibians, reptiles, etc. Their temperature varies with their surroundings. For example, the desert lizard basks in the sun during early hours when the temperature is quite low. However, as the temperature begins to rise, the lizard burrows itself inside the sand to escape the scorching sun. Similar burrowing strategies are exhibited by other desert animals.

(d) Importance of light to plant

Answer:

The ultimate source of energy for plants is sunlight. Plants are autotrophic organisms, which need light in order to perform the process of photosynthesis. Plants need the sun because sunlight is made up of electromagnetic radiations which are given off as energy to the plants. These electromagnetic radiation acts as the key factor in a process that is called photosynthesis. The photons of light energy are received by the chlorophyll molecules and they give off energy in the form of electrons. These electrons are than through a cyclic as well as non-cyclic flow are converted into chemical energy i.e. ATP and NADPH in the process of photosynthesis by which organic substances are formed in plants. Thus, light is a very important factor for plants and for the survival of all the components of Earth.

Class 12 Organisms and Populations NCERT Solutions:

(e) Effect of temperature or water scarcity and the adaptations of animals

Answer:

Effects of temperature or water scarcity and the adaptations of animals: Temperature is considered to be the most important ecological factor. The average temperature varies from one place to another and these variations in temperature affect the distribution of plants as well as animals on the Earth. There are animals which cannot tolerate a wide range of temperature and these animals are called stenothermal animals. The animals which can tolerate a wide range of temperature are called eurythermal animals. Some animals also undergo adaptations to suit their natural habitats. For example, the animals found in colder areas have shorter ears and limbs in order to prevent the loss of heat from their bodies. Similarly, animals like polar bears have thick layers of fat below their skin and thick coats of fur to prevent the loss of heat in polar regions. Some animals show adaptations like hibernation and aestivation to escape harsh winter and summer conditions respectively in order to respond against the temperature conditions.

Water scarcity is another factor that forces animals to undergo certain adaptations to suit their natural habitat. Adaptations of desert animals are mainly to conserve the water. For example, Animals found in desserts such as desert kangaroo rats, lizards, snakes, etc. are well adapted to their habitat. The kangaroo rat found in the deserts of Arizona never drinks water in its life. It has the ability to concentrate its urine to conserve water.

Organism and Population NCERT Solutions

Q15. With the help of suitable diagram describe the logistic population growth curve.

Answer:

Logistic population growth curve

The growth of a population takes place according to the availability of food, presence of predators and parasites, presence of other biotic and abiotic factors affecting a population and other conditions in a particular environment. There are two main types of models i.e. exponential growth model and the logistic growth model.

The logistic growth curve represents the logistic growth model. It represents growth when there is a competition between the individuals of a population for food and space. In this case, the fittest organism survives, reproduces and population growth is seen. In this type of growth, initially, a lag phase is shown which is followed by phases of acceleration and de-acceleration. The different phases of the logistic growth curve are:

1. Lag phase- In this phase, no growth is seen due to the absence of food and other resources.

2. Positive acceleration phase- Limited growth in population is seen as the resources become available.

3. Exponential growth phase- The population grows suddenly and show very rapid growth. The curve rises steeply.

4. Negative acceleration phase- In this phase, environmental resistance increases and growth rate of the population decreases.

5. Stationary phase- In this phase, the growth becomes stationary and becomes stable. The population is said to have reached the carrying capacity of the habitat.

A diagrammatic representation of Population growth curves is given below. The curve a represents exponential growth and curve b represents logistic growth

1650541475867

The equation of the logistic growth curve is as follows:

dN/dt = rN\left ( K-N/K \right )

Where N = Population density at time t

R = Intrinsic rate of natural increase

K = Carrying capacity
Since resources for growth for populations are finite and become limiting, the logistic growth model is considered a more realistic one.

Organism and Population NCERT Solutions:

Q16. Select the statement which explains best parasitism.

(a) One organism is benefited.

(b) Both the organisms are benefited.

(c) One organism is benefited, other is not affected.

(d) One organism is benefited, other is affected.

Answer:

(d) One organism is benefited, other is affected.

In parasitism, one organism lives on the body of another. In this interaction, the parasite gets benefitted while the host is negatively affected.

Class 12 Biology Ch 13 Question Answer

Q17. List any three important characteristics of a population and explain

Answer:

The term population refers to a group of individuals of any species living in a well-defined geographical area, sharing or competing for similar kind of resources and potentially interbreed. Some characteristics of the population are as follows:

1. Birth rate (natality)- It is the ratio of live births in an area to the population of an area. It is expressed as the number of individuals added to the population.

2. Death rate(mortality)- It refers to the live deaths in an area to the population of an area. It is expressed as the number of individuals removes from the population.

3. Sex ratio- It is the ratio of the number of male or female individuals per 1000 individuals.

4. Age distribution- A population at a given time is composed of different individuals belonging to different age groups. If the age distribution is plotted for the population, the resulting structure is called age pyramids. The shape of pyramids reflects the growth status of the population.

5. Population density- The number of individuals of a population present per unit area at a given time.

Questions related to CBSE Class 12th

Have a question related to CBSE Class 12th ?

Here are some options you can explore to get admission in a good school even though admissions might be closed for many:

  • Waitlist: Many schools maintain waitlists after their initial application rounds close.  If a student who secured a seat decides not to join, the school might reach out to students on the waitlist.  So, even if the application deadline has passed,  it might be worth inquiring with schools you're interested in if they have a waitlist and if they would consider adding you to it.

  • Schools with ongoing admissions: Some schools, due to transfers or other reasons, might still have seats available even after the main admission rush.  Reach out to the schools directly to see if they have any open seats in 10th grade.

  • Consider other good schools: There might be other schools in your area that have a good reputation but weren't on your initial list. Research these schools and see if they have any seats available.

  • Focus on excelling in your current school: If you can't find a new school this year, focus on doing well in your current school. Maintain good grades and get involved in extracurricular activities. This will strengthen your application for next year if you decide to try transferring again.

In India, the design and coding fields offer exciting career options that can leverage your interest in both. Here's how you can navigate this path:

Choosing Your Stream:

  • Graphic Design Focus: Consider a Bachelor's degree in Graphic Design or a design diploma. Build a strong portfolio showcasing your creative skills. Learn the basics of HTML, CSS, and JavaScript to understand web development better. Many online resources and bootcamps offer these introductory courses.

  • Coding Focus: Pursue a Computer Science degree or a coding bootcamp in India. These programs are intensive but can equip you with strong coding skills quickly. While building your coding prowess, take online courses in graphic design principles and UI/UX design.

Engineering Subjects (for a Degree):

  • Information Technology (IT): This offers a good mix of web development, networking, and database management, all valuable for web design/development roles.

  • Human-Computer Interaction (HCI): This is a specialized field that bridges the gap between design and computer science, focusing on how users interact with technology. It's a perfect choice if you're interested in both aspects.

  • Passing NIOS in October 2024 will make you eligible for NIT admissions in 2025 . NIT admissions are based on your performance in entrance exams like JEE Main, which typically happen in January and April. These exams consider the previous year's Class 12th board results (or equivalent exams like NIOS).

Here's why 2025 is more likely:

  • JEE Main 2024 Admissions: The application process for NITs through JEE Main 2024 is likely complete by now (May 2024). They consider your 2023 Class 12th marks (CBSE in this case).
  • NIOS Results: Since NIOS results typically come out after the NIT admission process, your October 2024 NIOS marks wouldn't be available for JEE Main 2024.

Looking Ahead (2025 Admissions):

  • Focus on JEE Main: Since you have a computer science background, focus on preparing for JEE Main 2025. This exam tests your knowledge in Physics, Chemistry, and Mathematics, crucial for engineering programs at NITs.
  • NIOS Preparation: Utilize the time between now and October 2024 to prepare for your NIOS exams.
  • Eligibility Criteria: Remember, NITs typically require a minimum of 75% marks in Class 12th (or equivalent) for general category students (65% for SC/ST). Ensure you meet this criteria in your NIOS exams.

Yes, scoring above 99.9 percentile in CAT significantly increases your chances of getting a call from IIM Bangalore,  with your academic background. Here's why:

  • High CAT Score: A score exceeding  99.9 percentile is exceptional and puts you amongst the top candidates vying for admission. IIM Bangalore prioritizes  CAT scores heavily in the shortlisting process.

  • Strong Academics: Your 96% in CBSE 12th and a B.Tech degree demonstrate a solid academic foundation, which IIM Bangalore also considers during shortlisting.

However, the shortlisting process is multifaceted:

  • Other Factors: IIM Bangalore considers other factors beyond CAT scores, such as your work experience (if any), XAT score (if you appear for it), academic diversity, gender diversity, and performance in the interview and Written Ability Test (WAT) stages (if shortlisted).

Here's what you can do to strengthen your application:

  • Focus on WAT and PI: If you receive a shortlist, prepare extensively for the Written Ability Test (WAT) and Personal Interview (PI). These stages assess your communication, soft skills, leadership potential, and suitability for the program.

  • Work Experience (if applicable): If you have work experience, highlight your achievements and how they align with your chosen IIM Bangalore program.

Overall, with a stellar CAT score and a strong academic background, you have a very good chance of getting a call from IIM Bangalore. But remember to prepare comprehensively for the other stages of the selection process.

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
