Carbon Cycle

The carbon cycle is a complex Earth system whereby carbon dioxide (CO2) is exchanged among four main regions of the planet. In the carbon cycle, CO2 is recycled through the atmosphere, biosphere, geosphere and oceans and other waterways in what are called "sinks" or reservoirs.

Carbon is the element on which the bodies of all living things are based. It is, generally obtained from carbon dioxide present in the air. Green plants and some bacteria consume carbon dioxide to make their own food.

          When these plants are consumed by the animals, they get some part of carbon. Carbon dioxide is released back into the atmosphere when the animals exhale. Carbon is returned to nature when the animals die. Decomposers such as worms, bacteria and fungi feed on dead animals matter and release carbon dioxide as they respire.
