Cycling Matter in an Ecosystem Carbon/Oxygen Cycle Water Cycle Nitrogen Cycle Phosphorus Cycle THE CARBON CYCLE

What Is Carbon? An element The basis of life of earth

Found in rocks, oceans, atmosphere Carbon Cycle The

same carbon atoms are used repeatedly on earth. They cycle between the earth and the atmosphere. Plants Use Carbon Dioxide Plants pull carbon dioxide from the

atmosphere and use it to make food photosynthesis. The carbon becomes part of the plant (stored food). Animals Eat Plants When

organisms eat plants, they take in the carbon and some of it becomes part of their own bodies. Plants and Animals Die When plants and animals die, most of

their bodies are decomposed and carbon atoms are returned to the atmosphere. Some are not decomposed fully and end up in deposits underground (oil, coal, etc.).

Carbon Slowly Returns to Atmosphere Carbon in rocks and underground deposits is released very slowly into the atmosphere.

This process takes many years. AKA the Carbon/Oxygen Cycle Cycle Repeats Over and

Over and Over and Over Its not necessarily in a circle but cycles throughout. Carbon in Oceans Additional carbon is stored in the ocean.

Many animals pull carbon from water to use in shells, etc. Animals

die and carbon substances are deposited at the bottom of the ocean. Oceans contain earths largest store of carbon. The Carbon Cycle

Human Impact Fossil fuels release carbon stores very slowly Burning anything releases more carbon

into atmosphere especially fossil fuels Increased carbon dioxide in atmosphere increases global warming Fewer plants mean less CO2 removed from atmosphere Water Cycle Condensation

Evaporation Precipitation Surface runoff Water Nitrogen Cycle
