Steph and Sam were having a debate about the steps in the carbon cycle. Steph states that living organisms only release carbon dioxide. How can Sam use the diagram above and Law of Conservation of Mass to defend his position?
Since the Law of Conservation of Mass states that mass cannot be created or destroyed, this diagram shows the absorption of oxygen in step 1 and step 3.
Since the Law of Conservation of Mass states that mass cannot be created or destroyed, this diagram shows the release of oxygen into the atmosphere in step 1 and step 3.
Since the Law of Conservation of Mass states that mass cannot be created or destroyed, this diagram shows the release of carbon dioxide and heat energy into the atmosphere in step 1 and step 3.
Since the Law of Conservation of Mass states that mass cannot be created or destroyed, this diagram shows the release of carbon dioxide, water, and heat energy into the atmosphere in step 1 and step 3.

A freshwater marsh is a type of ecosystem with all the trophic levels. Where the largest carbon reservoir would be located.
The largest carbon reservoir would be found in all living things because they exhale carbon dioxide.
The largest carbon reservoir would be found in the atmosphere and water because it transports carbon dioxide.
The largest carbon reservoir would be found in all living things and decaying materials because they are made up of carbon and other minerals.
The largest carbon reservoir would be found in the atmosphere, water, all living things, and decaying materials because carbon is conserved through the cycling of matter.
