Itâs theelement that anchors all organic substances, fromfossil fuels to DNA. On Earth, carbon cycles throughthe land, ocean, atmosphere, and the Earthâs interiorin a major biogeochemical cycle (the circulation ofchemical components through the biosphere from orto the lithosphere, atmosphere, and hydrosphere).
Carbon dioxide is a by-product of respiration ] and combustion combustion: Combustion is the process of burning by fire. . Green plants remove carbon dioxide from the atmosphere by photosynthesis. Living organisms-including all plants and animals-release energy from their food using respiration.Respiration and combustion-burning-both release carbon dioxide into the atmosphere. These processes form a carbon cycle in which the proportion of carbon dioxide in the atmosphere remains about the same.The animation should help you to understand how the cycle works.iving organisms-including all plants and animals-release energy from their food using respiration.
