 * In our garden the carbon cycle is involved in the process of photosynthesis. Below is a great link that has good animations explaining the process of photosynthesis. You can really see how the carbon atoms from carbon dioxide are rearranged to create new sugar molecules. **

Check the link below to learn more about the carbon cycle:

This link below describes the role of the carbon cycle and climate change. Follow the animation and take the quiz for each lesson.

EPA Carbon Cycle, Water Cycle, and Climate Change

another good link that discusses the carbon cycle and global climate change is below

 * Carbon Cycle Questions: **

An abiotic factor is air. (Oxygen or Carbon Dioxide)
 * 1. List two abiotic factors shown in the diagram above **

Another abiotic factor is fossil fuels. (carbon rich gasoline or oil)

Soil, temperature, sunlight, and water are other examples.


 * 2. List two biotic factors shown in the diagram. **

Plants Animals Insects bacteria ameoba decomposers fungi mold worms

One way that carbon enters the atmosphere is through the process of photosynthesis. Plants take in the Carbon Dioxide and water to convert it into Sugar ( carbohydrates) and oxygen.
 * 3. Identify different ways in which carbon enters the atmosphere. **

Fuels are burned and release Carbon Dioxide into the air. Combustion reactions produce lots of carbon dioxidel.

One way that it is removed from the atmosphere is through respiration. Another way is that when a living organism dies, the carbon is released into the air (in the form of carbon dioxide)
 * 4. Identify different ways in which carbon is removed from the atmosphere. **

One compound that contains carbon is sugar. Another compound that contains carbon is a fossil fuel.
 * 5. Name two different compounds in the diagram that contain carbon. **

Carbon is also found in Carbon Dioxide
