Answer: Plants use carbon dioxide and release oxygen. And animals release carbon dioxide and use oxygen.
Explanation:
During the process of photosynthesis, plants use light energy from the sun to convert carbon dioxide and water into chemical energy stored in carbohydrate molecules, such as glucose. During this process, they release oxygen as a waste product.
So, carbon is necessary for the creation of molecules. Also, plants and animals release carbon dioxide when they decompose, while animals also release carbon dioxide when they respire. This is because animals take in oxygen to perform aerobic respiration, and release carbon dioxide when they breathe, which is a waste product of cellular respiration. So, during this process, glucose and oxygen react together to produce carbon dioxide and water and releases energy.
Finally, carbon cycle refers to a cycle by which carbon is exchanged among the biosphere, it describes how carbon passes from animals to plants and vice versa.
As a summary of everythingt, we can say that plants use carbon dioxide to produce glucose and they release oxygen. And animals use this oxygen to perform cellular respiration consisting of the breakdown of glucose and this releases carbon dioxide as a waste product. Also, plants and animals release carbon dioxide when they decompose. In this way, the carbon cycle describes how it moves from plants to animals.
