Answer 2

Carbon dioxide is a green house gas. It spread a layer of carbon dioxide in the atmosphere of the earth. Similarly it is respiratory gas for plants at the day time by carbon dioxide it makes food for them in day time and release oxygen at day time.

At the same time if the gas carbon dioxide increases it is a harmful pollutant for us. Because we know the carbon dioxide is a green house gas it protects the earth from the cold. But if the amount of carbon dioxide increases it leads to global warming on the earth. It is harmful for us. It leads to dieses like astma and many more breathing problem for the human and animal also. At the same time we also know that plants take the carbon dioxide in day time but i did not take carbon dioxide in night time. It only take oxygen in night time and releases carbon dioxide like us. So like wise it increases in atmosphere. It is helpful for plant in day time only. On the another side if it incrases it leads many problem for us.
