A model of the carbon cycle typically shows that the amount of Earth’s carbon is constant. This is because the carbon cycle is a closed system in which carbon is exchanged between the atmosphere, oceans, soil, and living organisms, but the total amount of carbon remains relatively stable over time, although the distribution of carbon among different reservoirs can change.
