Describe the methods of carbon replenishment of atmosphere.

Carbon is replenished through carbon cycle in the atmosphere.

● Carbon cyle is the process in which carbon travels from the atmosphere into the organism and the Earth and then back into the atmosphere.

● Plants take carbon dioxide form the air and use it to make food.

● Animals then eat the food and carbon is stored in their bodies or released as CO2 through respiration. Thus carbon that was taken from the atmosphere as carbon dioxide by plants is returned back into the atmosphere by animals.
