Hint: Before answering this question, we should know that there are different types of allotropic forms of phosphorus. White phosphorus, black phosphorus and red phosphorus are different allotropic forms of phosphorus in nature. They have different properties and are different from each other.

Complete answer:
Phosphorus is present in the food in the form of phosphate and phosphate esters. Passive absorption in the small intestine is faced by phosphorus, some get absorbed by active transport as well. Phosphorus helps to regulate gene transcription, helps to maintain the pH in energy storage. It also activates the enzymes. Phosphorus forms 1-1.5% fat free mass. Our bones and teeth comprise 85 % and 15% are there all over the blood and soft tissues.
Black lights emit their light waves mostly outside the range which can be perceived by humans in the UV (ultraviolet) part of the spectrum. The black bulbs consist of phosphorus coating that absorbs UV light which is at the higher end. When an object which has a substance known as phosphorus is hit by a UV light wave, the phosphorus will glow naturally. Phosphorus coats the bulb. When a photon hits the phosphorus it forms heat and light.

Phosphorous is a vital mineral that is present organically in many foods and is taken as a dietary supplement too. Our bones, teeth, DNA, and RNA comprises phosphorus. Our cell membrane also has phosphorus in the form of phospholipids. It is a component in RNA as well.
