Carbon Cycle
By: Joey, Avery, Laela and Dana

2. Vocabulary to know Definition Of:
Source- Any process that releases more of the nutrient than it absorbs.
Sink- The opposite so any process that absorbs or stores more of the nutrient than it releases.

3. 2 processes that allow carbon to move from the atmosphere to the biosphere and back
Cellular Respiration-is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products(carbon).
Photosynthesis- is the process by which plants use the energy from sunlight to produce glucose from carbon dioxide and water. This glucose can be converted into pyruvate which releases adenosine triphosphate (ATP) by cellular respiration. Oxygen is also formed.

4. Humans Adding to Carbon Dioxide in the atmosphere
Burning trees
Burning Coal
Burning Oil
Burning Natural Gas

5. The effects of excess carbon in the carbon cycle
Melting Surface Ice- Warmer temperatures are causing sea ice to melt
Melting Land Ice- Warmer temperatures are melting glaciers
Rising Sea level- Melting land ice is linked to rising sea level
Changing Ocean Chemistry- Oceans warm sea water absorbs more carbon dioxide
Changing Ecosystems- Changing in temperature, ocean chemistry and sea level altering global ecosystems
Melting surface ice
Changing ocean chemistry
Melting land ice
Rising sea level
Changing ecosystems

6. How the Cycle works
Carbon enters the atmosphere as carbon dioxide from respiration and combustion.
Carbon dioxide is absorbed by producers to make carbohydrates in photosynthesis.
Animals feed on the plant passing the carbon compounds along the food chain. Most of the carbon they consume is exhaled as carbon dioxide formed during respiration. The animals and plants eventually die.
The dead organisms are eaten by decomposers and the carbon in their bodies is returned to the atmosphere as carbon dioxide. In some conditions decomposition is blocked. The plant and animal material may then be available as fossil fuel in the future for combustion.
