Question

write a note on how forests influence the quality of our air soil and water resources

Answer 1

Forests influence the quality of air, soil and water resources in the following ways

1. Influence of forests on air Both plants and animals release carbon dioxide to the atmosphere as a product of respiration. Forests take up this carbon dioxide for the manufacture of their food and release oxygen to the atmosphere after photosynthesis. In this way they are helpful in cleaning the air. Influence of forests on soil. Influence of forests on water- Forests lose water to the atmosphere through transpiration which is then converted into clouds, water vapours, etc. which are responsible for causing rain. Thus, forests help in increasing the water resources of the earth.

☆$\red {HELLO\:DEAR}$☆

Forests influence the quality of our air, soil, and water resources in various ways. Some of them are:

(i) Forests balance the percentages of carbon dioxide and oxygen in the atmosphere. The increasing amount of carbon dioxide caused by human activities is balanced by a larger intake of carbon dioxide by plants during the process of photosynthesis. Simultaneously, a large amount of oxygen is released.

(ii) Forests prevent soil erosion. Roots of plants bind the soil tightly in a way that the surface of the soil cannot be eroded away by wind, water, etc.

(iii) Forests help in the replenishment of water resources. During the process of transpiration, a huge amount of water vapour goes into the air and condenses to form clouds. These clouds cause rainfall that recharge water bodies.
