The Carbon Cycle
— Carbon can be stored in a variety of reservoirs, including plants and animals, which is why they are considered carbon life forms. Carbon is used by plants to build leaves and stems, which are then digested by animals and used for cellular growth. In the atmosphere, carbon is stored in the form of gases, such as carbon dioxide.

Carbon cycle
What is the carbon cycle? Carbon is transferred between the ocean, atmosphere, soil, and living things over time scales of hours to centuries.For example, photosynthesizing plants on land remove carbon dioxide directly from the atmosphere, and those carbon atoms become part of the structure of the plants. As plants are eaten by herbivores and …
