Carbon Cycle Quiz: What Do You Know?

Do you know anything about the carbon cycle? Do you think you can pass this quiz? The circulation of carbon occurs in a variety of forms through nature. Carbon is a fundamental component of all organic compounds, many of which are crucial to life on earth. The supply of carbon found in living matter is the carbon dioxide in the air or liquefied water. Take on this quiz to see how much you know about the carbon cycle.
