The Carbon Cycle Carbon is an essential element for all organisms. It is found in different forms in all four spheres of the earth. Six factors contribute to its cycling: 1. Photosynthesis - Plants use sunlight to “capture” carbon dioxide from the atmosphere (as CO 2 ) to make sugars. The chemical reaction is: light + 6CO 2 + 6H 2 O  C 6 H 12 O 6 + 6O 2 light + 6CO 2 + 6H 2 O  C 6 H 12 O 6 + 6O 2 (Sun’senergy) (carbon dioxide from the air) (waterfrom the soil) (produces) (sugar to make leaves…) leaves…) (oxygenreleased to the air)

6 Factors that contribute to the carbon cycle 2.Respiration – Process by which animals and plants (in the dark) use sugars to make energy and CO 2.The chemical reaction is: C 6 H 12 O 6 + 6O 2  6CO 2 + 6H 2 O + energy C 6 H 12 O 6 + 6O 2  6CO 2 + 6H 2 O + energy (sugars from food) (breath it in) (breath it out) (water in the body) (needed grow, move…) What do you notice about these two reactions? Answer: They are opposite! Plants produce the sugars and oxygen that animals need. Animals need plants to survive.

6 Factors that contribute to the carbon cycle 3.Food Chain: Carbon is also passed on from producers to consumers and moves up the food chain. 4.Decay: Decomposers break down dead plant and animal material. Some of the carbon is released as CO 2 into the atmosphere some of it enters the ground.

6 Factors that contribute to the carbon cycle 6.Carbon reservoirs: Carbon is stored in different parts of earth’s four spheres (eg. much CO 2 is dissolved in the oceans, carbon is stored in the earths crust as coal and fossil fuels) 5.Combustion: During the combustion of fossil fuels (oil, gasoline, natural gas) and forest fires, CO 2 is released into the atmosphere.
