A model of the carbon cycle typically illustrates that:
**a. the amount of earth's carbon is constant.**
The carbon cycle is a closed system, meaning that while carbon can change forms and move between different reservoirs (like the atmosphere, oceans, soil, and living organisms), the total amount of carbon on Earth remains relatively stable over long periods of time. However, the distribution and forms of carbon can change due to various processes such as photosynthesis, respiration, decomposition, and human activities like burning fossil fuels.
