A model of the carbon cycle typically shows that the amount of Earth’s carbon is constant. This is because, while carbon moves between different reservoirs (such as the atmosphere, oceans, soil, and living organisms) through processes like photosynthesis, respiration, and combustion, the total amount of carbon on Earth remains relatively stable over time.
