Use the explanations and the weblink below to create your own version of the carbon cycle.

Most of the chemicals that make up living tissue contain carbon. When organisms die the carbon is recycled so that it can be used by future generations. The model that describes the processes involved is called the carbon cycle.

Steps in the carbon cycle

1.Carbon enters the atmosphere as carbon dioxide from respiration and combustion.

2.Carbon dioxide is absorbed by producers to make carbohydrates in photosynthesis.

3.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.

4.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.

Carbon cycle in the sea

In the sea, marine animals may convert some of the carbon in their diet to calcium carbonate which is used to make their shells. Over time the shells of dead organisms collect on the seabed and form limestone. Due to Earth movements this limestone may eventually become exposed to the air where it's weathered and the carbon is released back into the atmosphere as carbon dioxide. Volcanic action may also release carbon dioxide.

Carbon enters the atmosphere as carbon dioxide from respiration (breathing) and combustion (burning).
