CARBON CYCLE: Describes the Movement of Carbon Molecules in the Environment

THE CARBON CYCLE

Diagram Showing the Carbon Cycle

EXPLANATION: RESPIRATION All Living Organisms will Respire Aerobically and Release Carbon Dioxide into the Atmosphere as Organic Compounds that are Broken Down to Release Energy PHOTOSYNTHESIS Photosynthesis Fixes Carbon Atoms from Atmospheric Carbon Dioxide into Organic Molecules and Becomes Part of Complex Carbon Compounds in Plants DECOMPOSITION Dead Organisms are Broken Down by Decomposers and Carbon in their Bodies are Returned to the Atmosphere as Carbon Dioxide COMBUSTION If Decomposition is Blocked, Plant and Animal Material are Available as Fossil Fuels After a Long Period of Time Combustion of Fossil Fuels Releases Carbon Dioxide Back into the Atmosphere
