Answer 2

Answer:

Plants and animals maintain the balance of carbon dioxide and oxygen in the air.

Explanation:

During photosynthesis, plants take in carbon dioxide from the air and release oxygen. This oxygen is taken in by living organisms which respire and release carbon dioxide. This dual process maintains the balance of carbon dioxide and oxygen in the air. This balance is disturbed when we cut down trees indiscriminately.
