Carbon cycle

• carbon cycle 


  The carbon cycle returns and takes carbon from the atmosphere

  
• How is carbon removed from the atmosphere and re emmited 


  • Carbon is removed from the atmosphere by producers (e.g. algae) who use it in photosynthesis.
  • By consuming plant matter, animals obtain carbon compounds.
  • Carbon is returned into the atmosphere (as carbon dioxide) 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
