Answers
Answer:
if we go on cutting trees then one time will come when there will be no tree and if there will be no there is no fruits with table and we will not get oxygen so we will also not there
if the top layer of the soil exposed then the plants will be note grown if they are not grown then also we will be not there because we depend on plant
(a) If we go on cutting trees.
If we go on cutting of trees, it will disturb the balance in the nature.
There will be an increase in the temperature of the earth which will result in global warming.
(b) The habitat of animal is disturbed.
Plants play a major role in the lives of animals
Animals are dependent on plants for their food, shelter and protection
If the habitat of animals is destroyed they would be forced to go to different places in search of food and habitat.
In this process the animals would get killed by other animals or humans.
Also,animals and birds do not get enough food in the absence of trees and plants as a result of which they starve to death.
(c) The top layer of soil is exposed.
Trees prevent soil erosion.
Less trees will lead to more soil erosion
Removal of the top layer of the soil will expose the lower layer which is hard and a rocky layerThis exposed layer is less fertile and contains less humus
thus, soil erosion leads to infertile and a barren land
