First, in the atmosphere, Carbon exists as CO 2, CH 4, and chlorofluorocarbons
Plants convert the carbon dioxide during photosynthesis, in turn releasing Oxygen.
Respiration of animals Decay of plants and animals (decomposers break it down and release as carbon dioxide) Combustion of organic material (fossil fuels) Production of cement Warming of oceans releases dissolved CO 2 Volcanic eruptions
