Question

107 Which processes maintain the balance of carbon dioxide and oxygen in the atmosphere? Describe.

Answer 1

Respiration and Photosynthesis are the two processes that maintain the balance of carbon dioxide and oxygen in the atmosphere.

All living organisms consume oxygen present in the air.

• The process of respiration uses oxygen present in the air, but this is constantly replaced by plants through the photosynthesis process. In this process, plants make their own food, and oxygen is produced along with it. Plants also consume oxygen for respiration, but they produce more than they consume.

• The balance of oxygen and carbon dioxide in the atmosphere is maintained through respiration in plants and animals and by the photosynthesis in plants. This shows the interdependence of plants and animals.
