Forests: Our Lifeline | Exercise

Question 1

Q1) Explain how animals dwelling in the forest help it grow and regenerate.

Solution:

Various types of animals (herbivores, carnivores, omnivores) live in forests and contribute to the food chain. Interconnection of the food chain will form the food web.

Animals help in dispersal of seeds from one part of the forest to another part. Animal’s excreta and their dead bodies when decomposed into soil act as manure for the plants. Microorganisms convert dead plants and leaves into humus which is rich in nutrients. Humus in soil provides necessary minerals for plant growth.
