Phosphorus Cycle

01Phosphorus Cycle

Phosphorus in organisms

This section covers the biological molecules containing phosphorus and how phosphorus passes between organisms by feeding.

Phosphorus in biological molecules

Plants and animals require phosphorus for the production of several important biological molecules.

  • phospholipids
  • nucleic acids, including DNA and RNA
  • ATP

Once phosphate has been taken up by a producer, its phosphorus can become incorporated into these biological molecules.

Transfer through feeding

Phosphorus passes from one organism to another when organisms feed. In this way, phosphorus in producers can enter consumers and can then pass onwards through feeding relationships.

Stage Form or location of phosphorus
Producer Phosphorus incorporated into biological molecules
Primary consumer Phosphorus obtained by feeding on producers
Further consumers Phosphorus transferred onwards during feeding
