4.9 Carbon cycle

1. Photosynthesis --> CO2 + H2O -----(photosynthesis)-----> Glucose +O2

--> CO2 is 003% of the atmosphere --> Plants reduce the atmospheric CO2

2. Feeding -->

Producer ---> Primary consumer (Takes the carbon) ----> secondary consumer

3. Respiration (waste = CO2) --> Glucose + O2 -----(enzymes)-----> Energy + CO2

= Respiration adds CO2

4. Decomposition --> When consumers and producers die, their organic molecules get broken down by bacteria and fungi, releasing more CO2 into the atmosphere

5. Combustion ---> Fossil fuels --------(combust)------> CO2

The same with cars, giving off CO2

Fossil Fuels
