9. How do plants and animals help each other in exchanging gases in the atmosphere?
Ans: All the animals require oxygen for their survival. It helps break down the digested food in the body and release energy. This process is called respiration. During this process, carbon dioxide gas is produced. Plants consume this carbon dioxide gas for preparing their food and release oxygen gas.
In this way, plants and animals help each other exchange gases in the atmosphere.
