Carbon cycle

  1. 1. Carbon cycleBTEOTSSSBAT understand the carbon cycle
  2. 2. Carbon cycleCarbon dioxide in the airRespiration and decayCarbon compounds inanimalsPhotosynthesisFeedingCarbon compounds inplantsBurningFossil fuels – oil, coal,peat, gas
  3. 3. •Carbon dioxide is removed from the environment by green plants and algae forphotosynthesis.•The carbon from the carbon dioxide is used to make carbohydrates, fats and proteinswhich make up the body of plants and algae.•Some of the carbon dioxide is returned to the atmosphere when green plants andalgae respire.•When green plants and algae are eaten by animals and these animals are eaten byother animals, some of the carbon becomes part of the fats and proteins which makeup their bodies.•When animals respire some of this carbon becomes carbon dioxide and is releasedinto the atmosphere.•When plants, algae and animals die, some animals (detritus feeders) andmicroorganisms (decomposers) feed on their bodies.•Carbon is released into the atmosphere as carbon dioxide when these organismsrespire.•By the time the microorganisms and detritus feeders have broken down the wasteproducts and dead bodies of organisms in ecosystems and cycled the materials asplant nutrients, all the energy originally captured by green plants has beentransferred.•Combustion of wood and fossil fuels releases carbon dioxide into the atmosphere.
