What cycle involves the exchange of carbon dioxide between plants and other organisms?

The carbon cycle is the process that involves the exchange of carbon dioxide between plants and other organisms. This cycle encompasses various biological and physical processes that allow carbon to move between the atmosphere, terrestrial ecosystems, and aquatic environments.

Plants play a crucial role in this cycle through photosynthesis, a process where they absorb carbon dioxide from the atmosphere and convert it into organic compounds, primarily in the form of glucose. When animals, including humans, consume these plants, the carbon is then transferred to them. Additionally, through respiration, animals release carbon dioxide back into the atmosphere, continuing the cycle.

The carbon cycle is linked to other cycles in nature, such as the oxygen cycle, but it is specifically focused on carbon and its various forms, including carbon dioxide, organic matter, and fossil fuels. This makes the carbon cycle integral to understanding ecosystems, climate change, and overall environmental health.
