Burning of fossil fuels and wood fires release carbon - stored in the fuels - as carbon dioxide into the atmosphere. Respiration by living organisms also releases carbon dioxide. Decay of organic matter releases carbon in the form of carbon - containing gases like carbon dioxide or methane. Photosynthesis, on the other hand, takes in carbon dioxide from the atmosphere to make organic compounds.
