B2 - The Carbon Cycle
1 Carbon Dioxide is taken from the atmosphere by plants for photosynthesis
1.1 Plants and animals respire, releasing Carbon Dioxide into the atmosphere
1.1.1 Animals eat plants and other animals so the carbon is passed through the bodies on the food web Microorganisms feed on the dead animals and plants and release carbon dioxide into the air through respiration. Organisms bodies get trapped under each other and fossilize (crude oil) HIGHER CARBON CYCLE Sea organism shells fall the the sea bed They follilisze to make limestone The underwater volcanos release carbon dioxide into the atmosphere Acid rain weathers the limestone and releases carbon dioxide Oceans can absorb the carbon dioxide from the air
1.2 When fuels are burnt (combustion) carbon dioxide return back to the atmosphere
