Photosynthesis and cellular respiration are super important for the carbon cycle! Photosynthesis happens in plants, algae, and some bacteria. During this process, these organisms take in carbon dioxide from the air and use sunlight to turn it into food, like glucose. On the other hand, cellular respiration happens in all living things. In this process, they break down the food to get energy, and as a result, they release carbon dioxide back into the air.
These two processes work together to keep the amount of carbon balanced in nature. Photosynthesis captures carbon, while cellular respiration releases it. This back-and-forth helps keep carbon moving around in different forms all the time!
