Recycling- the Carbon and Nitrogen cycle 

The Carbon Cycle

Carbon is one of a number of elements that are found in living organisms. Crabon needs to be recycled so that it can become available again to other living organisms.

  • Carbon dioxide is removed from the air by photosynthesis in plants
  • Feeding passes carbon compounds along a food chain or web

Carbon dioxide is released into the air by:

  • plants and animals respiring
  • soil bacteria and fungi acting as decomposers
  • the burning of fossil fuels (combustion)

Carbon dioxide is also absorbed from the air by oceans. Marine organisms make shells made of carbonate, which become limestone rocks.
