- The Carbon Cycle
- Stage 1
- Powered by photosynthesis- CO2 is removed from the atmosphere by green plants and algae and carbon is used to make carbohydrates, fats, proteins
- Stage 2
- Some carbon is returned to atmosphereas CO2 when plants and algae respire, rest moves throught the food chain
- Stage 3
- Some of the carbon is returned to the atmosphere as CO2 when animals respire
- Stage 4
- When plants, algae and animals die, detritus feeders and microorgansims feed on the remains
- When they respire CO2 is returned to the atmosphere
- When plants, algae and animals die, detritus feeders and microorgansims feed on the remains
- Stage 5
- Animals produce waste- broken down by detritus feeders and microorganisms
- Compounds in the waste are taken up from the soil by plants as nutrients - put back into the food chain
- Animals produce waste- broken down by detritus feeders and microorganisms
- Stage 6
- Some useful plants and animal products ie. wood and fossil fuels are burnt (combustion) and release CO2 into the atmosphere
- Stage 7
- Carbon is constantly being cycled- from the air, through food chains and eventually back to the atmosphere again
- Stage 1
