Ecosystems regulate the carbon cycle through various processes such as photosynthesis, respiration, decomposition, and carbon sequestration. Photosynthesis by plants and other autotrophic organisms helps remove carbon dioxide from the atmosphere and convert it into organic carbon compounds. Respiration releases carbon dioxide back into the atmosphere. Decomposition of organic matter by decomposers also releases carbon dioxide. Carbon sequestration involves storing carbon in vegetation, soils, and oceans, thereby reducing the amount of carbon dioxide in the atmosphere. Overall, these processes in ecosystems help maintain a balance in the carbon cycle.
