8. Exercise VIII

 

Plants prepare their food with the help of carbon dioxidenitrogenoxygen in the process of respirationtranspirationphotosynthesis. During this process, they produce nitrogen moreoxygen morecarbon dioxide more than they consume. The process of photosynthesis helps to balance oxygen and carbon dioxidenitrogen and carbon dioxideoxygen and nitrogen in the atmosphere which in turn help each other in the exchange of gases in the atmosphere.
