glucose + oxygen â carbon dioxide + water + energy. Respiration is also the process by which once-living (organic) organisms are decomposed. When organisms die, they are decomposed by bacteria. Carbon dioxide is released into the atmosphere or water during the decomposition process.
Another large natural source of CO2 includes the oceans. Carbon dioxide is also released by the burning of fossil fuels (coal, oil and gas) for power and electricity, and the production of cement. These are anthropogenic or man-made sources of carbon dioxide. Although man-made emissions of CO2 are significant, they are much smaller than natural emissions.
