| carbon cycle |
The cycle whereby carbon dioxide is fixed in living organisms by photosynthesis or chemosynthesis; is consumed in carbohydrate, protein, and fat by most animals and plants that do not carry out photosynthesis; and ultimately is returned to its original state when freed by respiration and by the death and decay of plant and animal bodies.

| carbon cycle |
Carbon is an essential element of life; it is necessary to form organic molecules, which are what makes up living tissue and sugars. Through photosynthesis, plants fix CO2 from the air into organic compounds, thereby incorporating it into their tissue. When an animal eats the plant, it is able to use that carbon inside its own body (animals cannot use atmospheric carbon). When the first animal is eaten by another, the carbon can then be used by the second, and so on. ...

| carbon cycle |
The circulation of carbon through ecosystems. Carbon atoms from carbon dioxide are incorporated into organic compounds formed by green plants during photosynthesis. These compounds are eventually oxidized during respiration by the plants, which made them, or by herbivores, carnivores and saprophytes, thus releasing carbon dioxide for further photosynthesis.
