Give reasons.

  1. Man modifies his environment
  2. Plants and animals depend on each other


  1. Man modifies his environment to meet his various needs. For example, he clears forests for obtaining land for agriculture and for making shelter. He extracts minerals from the earth for making various things. He makes dams for producing electricity. These are a few of the ways in which man modifies his environment.
  2. Animals, whether carnivores or herbivores, ultimately depend on plants for their food. Also, plants provide fresh oxygen to animals to breathe in. These keep the environment clean and provide shelter to a number of animals. On the other hand, animals provide carbon dioxide which plants use for making their food. Dead and decaying matter of animals provides nutrients to plants to help them grow.
