8) Aquatic organisms make their hard shells from carbon they absorb from
9) Levels of carbon dioxide in the air have increased significantly over the last 100 years. This is largely due to
10) Explain how carbon dioxide contributes to climate change.
Above is a simplified diagram of the amount of carbon stored in different carbon sinks and the amount that cycles between the carbon sinks in gigatons.
The white writing represents carbon in carbon sinks while the yellow represents the flow of carbon between carbon sinks each year.
The image above was obtained from http://genomics.energy.gov.
Draw the diagram above on a butcher's paper.
Indicate with arrows the flow of carbon amongst the different carbon sinks shown.
Label the following terms on your diagram and give a one sentence explanation as to its impact on the carbon cycle.
On the same paper draw how the following forms of energy are generated. For each discuss the following points
What is carbon sequestration? Give an example of how this is applied to reducing carbon dioxide emissions.
