THE CARBON CYCLE

  • Carbon exist as C02 in nature. Green plant absorb C0from the atmosphere to form carbohydrate
  • Animal obtain their carbon by fading in green plant
  • Carbon can be released in the form of C0to the atmosphere when fossil fuel are born
  • When plant and animal die sapropythic bacteria and fungi cause the decay of their dead body releasing C02  to the atmosphere
  • During volcanic erosion a small amount of C02  is released to the atmosphere
