Science 10 Data Booklet

Shows Three Parts to the cycle 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 CO 2 + H 2 O -> C 6 H 12 O 6 + O 2

Cycling carbon comes in four pathways 1)Photosynthesis: Plants use carbon dioxide and water to make sugar and oxygen CO 2 + H 2 O -> C 6 H 12 O 6 + O 2 2) Cellular respiration: Animals and plants breakdown sugar to make carbon dioxide and water C 6 H 12 O 6 + O 2 -> CO 2 + H 2 O

Cycling carbon comes in four pathways 3) Decomposition: Bacteria and fungi break down organisms into organic matter

Cycling carbon comes in four pathways 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.
