Question

briefly explain carbon cycle under 5-10 lines

Answer 1

The major source of carbon in the atmosphere comes from carbon dioxide. Carbon dioxide enters the atmosphere through respiration and combustion process. The process of photosynthesis involves the absorption of CO2 by plants to produce carbohydrates and the equation is as follows.

CO2 + H2O + energy → CH2O +O2

Carbon compounds are passed along the food chain from the producers to consumers. The majority of the carbon exists in the body in the form of carbon dioxide through respiration. The role of decomposers is to eat the dead organism and return the carbon from their body back into the atmosphere and the equation goes like these:

CH2O +O2 → CO2 + H2O
