There are some organisms like humans who eat other plants and animals in order to create energy. These organisms take in oxygen and expel carbon dioxide. Then, there are other organisms that you a process called photosynthesis in order to convert the light from the sun into usable energy. These organisms, mostly plants, take in carbon dioxide and expel oxygen. Thus, both kinds of organisms are in a mutually-beneficial relationship that helps support all life. ADP and ATP ATP (Adenosine triphosphate) is a molecule in the body that cells use for energy transfer. When an organism processes food, it creates ATP in cells. Each molecule of ATP has three branches or phosphate groups that can be broken off. When a c
