Explain the role of forest in maintaining the balance between oxygen and carbon dioxide in the atmosphere.

Forests are called the green lungs. This is because plants in forests release oxygen through the process of photosynthesis and help in providing oxygen to animals for respiration. Plants consume carbon dioxide released by the animals. In this way, plants help in maintaining a balance of oxygen and carbon dioxide in atmosphere.

Forests absorb atmospheric carbon and replenish the oxygen in the air we breathe.

Forests during daytime convert CO₂ to oxygen by using CO₂ for photosynthesis. Thus they regenerate the oxygen consumed by humans and other living beings and maintain the balance of CO₂ and oxygen.
