D is answer simple

Ans 2:

Class : Class 6
Ans is D because top soil erosion will occur. Because of less trees, there will not be enough supply of food, so herbivores will become extinct, if there will no herbivores, there will be no carnivores and omnivores also. As carbon dioxide is a greenhouse gas, more amount of carbon dioxide will cause global warming. And trees are used to make some medicines, so if trees wil be not there, this will lead to loss of some medicines.
