Solution

(a) Plants absorb water from the soil and evaporates it to form clouds. Deforestation leads to cutting down of trees. As a result less water is absorbed from the soil and it disturbs the water cycle. The formation of clouds becomes difficult which leads to reduced rainfall.

(b) Trees play a vital role in the equilibrium of the ecosystem. Deforestation is a process of cutting trees to make space for pastures or for industries and households of the ever-increasing human population.
