Question

Which of the following does not have a effect on the forest ecosystem?

• A. Deforestation
• B. Soil erosion
• C. Climatic variation
• D. None of the above

Answer 1

The correct option is D None of the above

Forests are extensive self-sustained wooded tract of lands with a biotic community predominated by woody vegetation consisting of trees and shrubs with a close canopy.

Forests contain 90 per cent of terrestrial biomass. Forests suffer damage due to soil erosion, deforestation and climate changes.

Soil erosion directly depletes the productivity of land, so that it cannot support vegetation.

Deforestation means loss of forests due to natural or anthropogenic activities.

Climate changes adversely affect the animal and plant life forms inhabiting the forests.
