  • How is carbon involved in photosynthesis?
    Carbon in fossil fuels is released through burning.
    Organisms release carbon from bodies of dead animals.
    Plants use carbon from carbon dioxide to make glucose.
    Animals break down the glucose to release carbon in CO2.
  • Carbon dioxide is also released from rock through weathering and erosion.
