B2 - The Carbon Cycle

B2 - The Carbon Cycle

1. Carbon Dioxide is taken from the atmosphere by plants for photosynthesis

   • Plants and animals respire, releasing Carbon Dioxide into the atmosphere
     • 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
   • When fuels are burnt (combustion) carbon dioxide return back to the atmosphere
