Question

How does photosynthesis and respiration help in maintaining the O₂ and CO₂ cycle?

Answer 1

Photosynthesis:

1. The process by which green plants make their own food with the help of carbon dioxide, water in the presence of sunlight and chlorophyll is known as photosynthesis.
2. During the process of photosynthesis, oxygen is released into the atmosphere.

Respiration:

1. Respiration is the process of release of energy by breaking down food molecules(glucose) that are stored in the body cells.
2. During respiration, carbon dioxide, energy and water are released.

Role of forest in the maintenance of O₂ and CO₂ cycle:

1. Forests play a significant role in maintaining the balance between oxygen and carbon dioxide in the atmosphere.
2. The plants present in forests release oxygen through the process of photosynthesis that supports different life forms on earth.
3. Plants take in carbon dioxide released by the animals during respiration and utilize it in the process of photosynthesis. Thus, the forests create a balance between oxygen and carbon dioxide in the atmosphere.
