Carbon Cycle Diagram. Getting background knowledge for a scientific investigation. See carbon cycle diagram stock video clips.
One dealing with rapid carbon exchange among living organisms. Carbon is present in carbon based molecules that are integral to all living creatures as carbon dioxide and methane in the atmosphere in carbonate rocks in the lithosphere and as organic molecules in soils and sediments which are derived from formerly living material. The carbon cycle leads to the movement of carbon between the earths biosphere geosphere hydrosphere and atmosphere.
Carbon enters the atmosphere through natural processes such as respiration and industrial applications such as burning fossil fuels.
There are also exchanges with the ocean which are only hinted at here. The sizes of reservoirs are in units of gigatons of carbon gtc. This depiction of the carbon cycle focusses on the terrestrial land based part of the cycle. Yellow numbers are natural fluxes and red are human contributions in gigatons of carbon per year.
