- The carbon cycle
- Energy in the carbon cycle
- Energy is transferred in the carbon cycle.
- During photosynthe-sis energy from sunlight is transferred and stored as chemicals in carbohydrates.
- Some of this energy is transferred to other organisms (such as animals/dec-omposers) when they feed on the plant
- Some of the energy is wasted, heating the soil and the air.
- The process of the carbon cycle.
- Animals, plants and decomposersall interact with each other in the carbon cycle.
- Photosynthe-sis converts carbon dioxide into carbohydrateand other food molecules such as proteins.
- Carbon dioxide + water = glucose + oxygen.
- When animals eat plants or other animals the food goes into their cells and is broken down by respiration.
- Glucose + oxygen = carbon dioxide + water.
- Carbon dioxide is returned into the air when animals breathe out.
- Plants and micro organisms also respire.
- Some dead organisms do not decay they become buried and compressed, deep underground and change into fossil fuels.
- Carbon dioxide is returned to the air again when wood or fossil fuels are burnt (combustion).
