Question

Name the processes which maintain the balance between oxygen and carbon dioxide in the air. How is it done?

Answer 1

Respiration and combustion are the processes which maintain the balance between oxygen and carbon dioxide in the air.

Respiration is the chemical process that takes place in all living beings. In this process, oxygen present in the inhaled air reacts with the digested food material in the body. This results in the release of energy, carbon dioxide and water.
