Why is phosphorus important to us in APES?

• it works alongside the nitrogen cycle to fertilize plants

• it is the primary component of mountains, which serve as habitats for animals

• it enhances decomposition of organic matter

• it is a component of many biological molecules, such as nucleic acids, some lipids, ATP, and bony structures
