When condensation hits rocks, it causes the phosphorus from the rocks to go into the soil, and with organisms waste and decomposing, the phosphorus from in that then goes into the soil as inorganic phosphorus.
Waste and decomposition
Plants will take in phosphorus from the ground that the weathering rocks have left in the soil. Like animals, when plants die, they will leave phosphorus in the ground.
All animals will get their phosphorus from plants, for herbivores that is the only phosphorus source. Omnivores have plants and other animals they can get it from. Carnivores have to resort to other animals as their phosphorus source.
Inorganic phosphate when it hasn't been taken up by plants can be made into new rocks. Inorganic phosphate can go through mineralization and then be made into new sedimentary rocks. Then the rock that is deep below the surface can go through geological uplift, and then be new rocks on the surface.
Sedimentary rocks that are rich with phosphorus with life up to the surface.
Phosphorus is very important in all living organisms, even though it only makes up one percent of a living organism. Phosphorus is an essential nutrient. It plays a critical role in cell development and is a key component of molecules that store energy, such as ATP, DNA, and lipids.
We all need phosphorus!
The phosphorus cycle is almost entirely dependent on starting by the water cycle. The water cycle erodes the rock with precipitation.
