Carbon moves through the environment in a continuous cycle, shifting between reservoirs such as plants, animals, soil, air, water, and rocks. Key processes—photosynthesis, respiration, decomposition, and combustion—drive this movement. While the biological carbon cycle happens quickly, the geological carbon cycle takes millions of years. Human actions can disrupt this cycle, contributing to climate change.
