Question

Philoid · Accepted Answer

(a) True

Reason- Forests keep a check on climate, water cycle and air quality. Forests maintain the climate and water cycle through rain and air quality by maintaining the carbon dioxide and oxygen level in the environment.

(b) False.

In a forest, trees form the uppermost layer, followed by shrubs. The herbs form the lowest layer of vegetation.

Reason- Herbs are smaller than shrubs.

This is a picture showing difference in the height of herbs, shrubs and trees.

(c) True

Reason- The forest keeps on changing as the climate conditions changes. New plants are grown by the seed dispersed by animals or air.

(d) True

Reason- The forest helps in prevention of soil erosion as the roots bind to the soil and hence does not allow the removal of the top layer of soil.
