Essay Questions (The following questions are VERY similar to what you will see on your test. They are NOT required for points on this study guide, but it would be very beneficial to familiarize yourself with them and use them to prepare for the test!!):

**You get to SKIP question #15 on the test! Just write SKIP in the box!

Yes/No (I know this and can explain to a friend.)
Essay Question


Describe the steps of the carbon cycle, making sure to discuss both living and nonliving components of the cycle


Describe what would happen if one of the carbon reservoirs were missing. How would that impact the carbon cycle? Would it be able to continue?


Provide at least 2 ways that carbon levels can be reduced in the atmosphere.


Compare and contrast how photosynthesis and cellular respiration contribute to the carbon cycle
