the global carbon cycle

The global carbon cycle is the movement of carbon among the Earth's atmosphere, oceans, soil, and living organisms. Carbon exists in various forms, such as carbon dioxide in the air and organic matter in plants and animals. Through processes like photosynthesis, plants absorb carbon dioxide and convert it into biomass. When plants and animals respire, decay, or burn, carbon returns to the atmosphere. Oceans also absorb and release carbon. Human activities, especially fossil fuel combustion, have added extra carbon to the cycle, contributing to climate change. Understanding this cycle is vital for addressing environmental challenges.
