Detailed explanation-1: -Phosphorus, as phosphate (PO4-3), is an essential element of life. It does not cycle through atmosphere, thus enters producers through the soil and is cycled locally through producers, consumers and decomposers. Generally, small local losses by leaching are balanced by gains from the weathering of rocks.

Detailed explanation-2: -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-3: -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-4: -In calcareous soils, soluble phosphorus in the soil solution reacts with Ca to form low solubility Ca phosphates. The Phosphorus Cycle is the biogeochemical cycle that describes the transformation and translocation of phosphorus in soil, water, and living and dead organic material.
