Question

Explain carbon cycle.

Answer 1

• The carbon cycle is an important biogeochemical gaseous cycle. Carbon dioxide is present in the atmosphere is abundant.
• Plants use the carbon in the process of photosynthesis. In this process, sunlight and carbon dioxide are used to form a carbon compound called glucose, which is used by other living organisms. In this way, atmospheric carbon comes in every organism. To make the balance, it is necessary to recycle back this carbon in the atmosphere. It is done by several processes.
• The process of respiration breaks down glucose molecules to liberate carbon dioxide. Carbon dioxide is also liberated in the atmosphere by the process of decomposition of the dead organic matter. Combustion of fuels, industrialization, forest fires, volcanic eruptions, deforestation is also the sources of carbon dioxide. Again the process continues to complete the cycle.
