9. Explain why there is a need of variety of animals and plants in a forest.class 7​

Answer 1

Answer:

Forests are the essential life on earth. All plants and animals continue to live in forest life. ... When animals and plants die, the various microorganisms present in the soil helps to convert the dead and decayed matter into humus and thus the fertility of soil can be increased which boosts up the plant growth.

Answer 2

A greater variety of plants and animals in the forests helps it to regenerate and grow. Greater variety of plants means more food and habitat for the herbivores. An increase in herbivores means more food for carnivores. Decomposers help to maintain the supply of nutrients to the soil and to the growing plants.
