Answer 2

The carbon cycle with the help of a simplified model:

• Carbon is fixed during photosynthesis in plants.
• Co2 is returned to the atmosphere in large amounts by the respiratory activities of organisms.
• By acting on the waste materials and dead organic matters decomposers contribute Co2.
• Some of the fixed carbon is lost to the sediments and removed from circulation.
• Burning of fossil fuels, forest fire and combustion of organic matters volcanic activity also release Co2 in the atmosphere.
