Carbon is released into the atmosphere only during the burning of fossil fuels
Explanation:
During the process of fuel burning, carbon is released in the atmosphere. The human invented power plants, factories, cars and other vehicles releases carbon in the form of carbon di-oxide in atmosphere.
However, the cellular respiration is similar to that of fuel burning as it is too a combustion process. But the carbon produced in this process fuels the inner cellular activities rather than releasing it in the atmosphere.
