1) Cycling Carbon: The carbon that is moving through the ecosystem

2) Stored Carbon: The carbon that is not available

3) Carbon exchange: The trade off. How much is going in and how much is going out of a store

Science 10 Data Booklet

Cycling carbon comes in four pathways

1) Photosynthesis: Plants use carbon dioxide and water to make sugar and oxygen

CO2 + H2O -> C6H12O6 + O2

Cycling carbon comes in four pathways

1) Photosynthesis: Plants use carbon dioxide and water to make sugar and oxygen

CO2 + H2O -> C6H12O6 + O2

2) Cellular respiration: Animals and plants

breakdown sugar to make carbon dioxide and water

C6H12O6 + O2 -> CO2 + H2O

3) Decomposition: Bacteria and fungi break down organisms into organic matter

4) Food Web: Carbon moves between plants

and animals during the food web interaction(Eg. Carbon from plants moves into deer)

Carbon Exchange

• Carbon Moves in and out of stores at certain rates: – The up arrow shows carbon leaving the store. – The down arrow shows carbon entering a store

Carbon Stores

• Long term storage of carbon. This carbon is not yet available to the biotic factors in the ecosystem.
