4. How does the carbon cycle support the Law of Conservation of Mass? A. The total amount of carbon decreases, as it moves through the carbon cycle. B. The total amount of carbon gradually increases, as it moves through the carbon cycle. С. The total amount of carbon is constant but limited as it moves through the carbon cycle. D. The total amount of carbon changes depending on where its located in the carbon cycle.
