The Carbon Cycle is a cycle in which carbon is exchanged amongst the biosphere and the atmosphere. Carbon is cycled through the ground, air, plants, animals, and fossil fuels. When animals or humans breathe out, they breathe out carbon dioxide. This carbon dioxide is goes into the atmosphere, and is then absorbed by the ocean, plants, or trees to help grow. Once these animals or plants die, they are able to be turned into fossil fuels. Once fossil fuels are burned, more carbon dioxide is distributed into the atmosphere. The carbon is the absorbed by the plants and animals again, continuing the carbon cycle.
