The importance of the carbon cycle in the environment lies in its role in regulating climate and supporting life. Carbon is a fundamental building block of organic molecules and is essential for photosynthesis and respiration. The cycle involves the movement of carbon through various reservoirs, including the atmosphere, oceans, and terrestrial ecosystems. By cycling carbon, ecosystems maintain energy balance and enable the production of food resources. Disruptions to this cycle can lead to climate change and affect global biodiversity.
