NCERT Solutions for Class 8 Science Chapter 7 Conservation of Plants and Animals: Paheli and Boojho's Questions
Class 8 science chapter 7 question answer for Intext questions and exericse are given below :
Paheli's Question (Page number - 77)
Q. What is the purpose of making national parks, wildlife sanctuaries and biosphere reserves?
Answer:
The main purpose of making national parks, wildlife sanctuaries and biosphere reserves is to protect the animals from an external threat like prevent from hunting and other danger.
And also to maintain their natural habitat as well as their own environment.
Boojho's Question (Page Number- 77)
Q. How does deforestation reduce rainfall on the one hand and lead to floods on the other?
Answer:
Deforestation means cutting down the trees. And we know that trees play an essential role in the water cycle as it contributes moisture to the air which brings rainfall. So if no. of trees decreases the process of transpiration and water cycle gets disturbed. Hence rainfall will be reduced.
Reduced rain will reduce the amount of water absorption in the soil. This soil will be dry and leads to lower water intake in the trees, and because of that, soil erosion will occur, and it leads to floods.
Activity 7.2 (Page Number - 78)
Q. Animal life is also affected by deforestation. How?
Answer:
Animal life is also affected by deforestation because wild animals lose their shelter and food amount is decreased. So, they start migrating for the search of the food, in this process they might get killed by other animals or hunters. In this way, their life will be affected by deforestation.
Paheli's Question (Page number - 83)

Q3. Discuss the effects of deforestation on the following. (b) Environment
Answer: Due to deforestation, unbalancing is happen between carbon dioxide and oxygen. Also, it affects the climate of the surrounding environment. Global warming is increased because of the increase in the amount of carbon dioxide.
Q3. Discuss the effects of deforestation on the following- (c) Villages (Rural areas)
Answer- Because of deforestation, in rural areas, the level of groundwater goes down which means access to potable water becomes difficult. Also, more chance of soil erosion is occurring because plant roots that hold the soil particle together is been removed also the fertility of the soil is decreased.
Q3. Discuss the effects of deforestation on the following. (d) Cities (Urban areas)
Answer:- Effects of deforestation on cities:
It can increase the chances of natural calamities like a flood or heavy rainfall. Also, it can lead to global warming because of the increase in the level of carbon dioxide in the atmosphere because of vehicular and industrial pollution. Increase in temperature also disturbs the water cycle.
Q3. Discuss the effects of deforestation on the following. (e) Earth
Answer:
Deforestation disturbs the whole ecological system. As a result of deforestation, an increase in chances of the flood, soil erosion, drought, and desertification increases. Also, increase global warming due to the increase in the level of carbon dioxide. As a result, the total water cycle gets disturbed and also the level of potable water goes down.
Q3. Discuss the effects of deforestation on the following. (f) The next generation
Answer:
Effect of deforestation on the next generation- Deforestation causes many problems such as drought, floods, soil erosion, greenhouse effects, and other global issues, etc. And after all, the consequences of these will affect the future generation.

Q4. What will happen if.
(a) we go on cutting tree
(a) we go on cutting trees
Answer: If we go cutting the trees, the life of animals and their habitat will get completely vanished.
And because of it, the ecological balance is disturbed. The biodiversity of many areas will be destroyed completely.
Also global warming increase and due to it, the desertification will happen which lead to soil erosion and also more chance of drought.
(b) the habitat of an animal is disturbed
Answer:
If the habitat of animals is disturbed, it means their home and foods all are going to have vanished for them.
So they start migrating to the land areas for the search of food and shelter, where people live, and this is dangerous for those people.
Also, animals can get killed by others. As a result whole ecological system is starting to unbalancing.
(c) the top layer of soil is exposed.
Answer:
If the top layer of soil is exposed, then it will gradually be exposed to the lower layer of the soil which is mostly rocky and hard in nature.
And this is less fertile because it has less humus.
If the soil erosion is continuously occurring then the land becomes completely fertile.
Q5 (a). Answer in brief.

NCERT Solutions for Class 8 Science Chapter 7 - Conservation of Plants and Animals
Answer:
No, It is not at all justified to cut trees to meet the ever-increasing demand in factories and for shelter. Forests are the home for many organisms such as wild animals. Basically, forests are home for the wild animals and they provide us a good quality of air as they give out oxygen and absorbs the carbon dioxide from the surroundings.
They prevent the excess heating of the atmosphere; also they prevent soil erosion. Trees help to increase the fertility of the soil and also preserve biodiversity. To fulfill the need of the human population, we have been cutting so many trees, and as a result, we have to face many problems like global warming, soil erosion, and droughts, etc.
Hence we cannot afford to cut more trees, and we need to save them.
Answer:
We can contribute to the maintenance of green wealth of our locality by following ways-
- By taking cares of plants and trees of our surroundings. We can do more number of planting.
- To encourage the people of my area to plant more trees by telling them about the importantness of trees.
- We can aware the young children by telling them the consequences of deforestation and how they affect the environment.
- And also keep watering the plants, so that they can grow healthy and easily.
Q8. Explain how deforestation leads to reduced rainfall.
Answer:
Deforestation means the removal of trees or plants from an area for different purposes.
We know that plants absorb carbon dioxide from the atmosphere. and if there is no plant, the level of carbon dioxide in the atmosphere will rise.
These lead to increasing the temperature of the earth, and it will disturb the water cycle. As a result of the disruption in the water cycle, also affect the rainfall pattern.
