Question 1 Report

The falling off of leaves of deciduous trees is helpful to the plant because it
Answer Details
The falling off of leaves of deciduous trees is helpful to the plant because it reduces the rate of transpiration. Deciduous trees shed their leaves during the dry season to conserve water. The leaves of these trees have stomata that can lose water through transpiration. Shedding of leaves helps reduce the surface area of the plant that can lose water through transpiration, thus conserving water. Additionally, the fallen leaves decompose, adding nutrients to the soil, which are later used by the plant to produce new leaves.
