Briefly describe the carbon cycle

What will be an ideal response?


Answer: The carbon cycle is the movement of carbon among the atmosphere, hydrosphere, biosphere, and lithosphere as a result of processes such as photosynthesis and respiration, sedimentation, weathering, and fossil-fuel combustion

In the carbon cycle, carbon in the form of atmospheric carbon dioxide (CO2) is incorporated into carbohydrates in plant tissues through photosynthesis. Animals consume plants and use the plant carbohydrates for their own life processes. Carbon is stored in biomass and animals. Through respiration, carbon is returned to the atmosphere as CO2. It is also added to the atmosphere by the
combustion of fossil fuels. These three processes - photosynthesis, respiration, and combustion help cycle carbon and oxygen back and forth between living things and the environment.
