Carbon cycle

• Carbon cycle:

  • Carbon is removed from the atmosphere by producers, by using it in photosynthesis.
  • By consuming plant matter, animals obtain carbon compounds.
  • Carbon is returned into the atmosphere because of the respiration that happens in plant and animal cells.
  • When animals and plants die, decomposers return the carbon locked in their bodies back to the atmosphere via decay.
  • Combustion of fossil fuels is another source of carbon entry into the atmosphere.
