<span>ATM is shortened adenosine triphosphate. This is required by all living cells as this serves as the continual supply of energy which keeps the organism alive.

<span>Phosphorus cycles between living things and the environment, particularly the soil. This is the case with many other substances as well such as carbon.

When the animal dies, its remains are decomposed and the constituent ions are released into the soil, after which they are taken up by plants. Animals consuming these plants gain the phosphorus again, and the cycle continues.</span>
