Carbon Cycle

• -Respiration->occurs in plant and animals->co2 is released into the atmosphere.
• -photosynthesis->occurs in plants->co2 diffuses into plant cell and is used in photosynthesis
• -Decomposition->co2 is released into the atmosphere when decomposers respire and co2 is used to make complex carbon compounds.
• Feeding->Animals eat plant which contain carbon compound which is broken down to use respiration.
• Combustion->dead plants are changed by heat and pressure in to fossil fuels when burnt release co2.
