Can you explain phosphorous cycle in easy way?

Phosphorous is an important component of many of our cells. Phosphorus is most commonly found in rock formations and ocean sediments as phosphate salts. Phosphate salts that are released from rocks through weathering usually dissolve in soil water and absorbed by plants.

Animals absorb phosphates by eating plants or plant-eating animals.
When animals and plants die, the phosphorous become available to decomposers and returns to the soils or oceans. the decomposers break down the tissues and release phosphate into soil from where plants take it up again.

 from land it moves to the oceans and water bodies and incorporates in the marine food chain. After that, phosphorus will end up in sediments or rock formations again, remaining there for millions of years. Eventually, phosphorus is released again through weathering and the cycle starts over.
Human activities have also add up and changed the natural cycle by activities such as mining and fertilizing. extra phosphorous is add up in the water bodies and give an advantages to some marine organisms thus disturbs the natural cycle.
