Detailed explanation-1: -Phosphorus can be found on earth in water, soil and sediments. Unlike the compounds of other matter cycles phosphorus cannot be found in air in the gaseous state.

Detailed explanation-2: -There are no major gaseous forms of phosphorus, so aside from wind distributing small particles of dust containing phosphorus, only very small amounts of phosphorus move through the atmosphere.

Detailed explanation-3: -The role of phosphorus in animals and plants Phosphorus is an essential nutrient for animals and plants. It plays a critical role in cell development and is a key component of molecules that store energy, such as ATP (adenosine triphosphate), DNA and lipids (fats and oils).
