A model of the carbon cycle typically shows that the amount of Earth's carbon is constant over long timescales. While carbon can move between different reservoirs (such as the atmosphere, oceans, soil, and living organisms), the overall amount of carbon on Earth does not increase or decrease significantly in the long term. Therefore, the correct response would be: The amount of Earth’s carbon is constant.
