4.9 Carbon Cycle

describe the stages in the carbon cycle including respiration, photosynthesis, decomposition and combustion.

1. Photosynthesis = CO2+H2O -chl&light-> C6H12O6 + O2 = 0.03% of atmospheric carbon

2. Feeding = Producer -carbon-> primary consumer -carbon-> secondary consumer

3. Respiration = C6H12O6 + O2 -enzyme-> energy + CO2 + H2O

4. Decomposition = death of organic molecule -bacteria&fungi-> CO2

5. Combustion = Fossil fuels (oils, coals) -industrial/motor-> CO2
