How does forest help in maintaining the balance of oxygen and carbon dioxide in the atmosphere? [5 MARKS]
The green plants and trees present in the forest utilize carbon dioxide from the environment during the process of photosynthesis and release oxygen into the atmosphere. This oxygen is inhaled by the animals during respiration. Animals release carbon-dioxide during respiration which is absorbed by plants. In this way, the oxygen and carbon dioxide cycle go on. Since forests contain a large number of plants and trees, they help in maintaining the balance between oxygen and carbon dioxide in the atmosphere.
