What is the carbon cycle?

Back

The carbon cycle is the process by which carbon is exchanged between the atmosphere, land, water, and living organisms. It involves various processes such as photosynthesis, respiration, decomposition, and combustion.

What is respiration in the context of the carbon cycle?

Back

Respiration is the process by which living organisms, including plants and animals, release carbon dioxide back into the atmosphere by breaking down glucose for energy.
