The phosphorus cycle is the biogeochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere. Unlike many other biogeochemical cycles, the atmosphere does not play a significant role in the movement of phosphorus, because phosphorus and phosphorus-based compounds are usually solids at the typical ranges of temperature and pressure found on Earth. Phosphates move quickly through plants and animals. The processes that move them through the soil or ocean are very slow, making the phosphorus cycle overall one of the slowest biogeochemical cycles. Losses occur in terrestrial environments by A) mineral surfaces. B) leaching and erosion. C) microbial action on humus and manure. D) plant uptake in the form of fertilizers.

The phosphorus cycle is a blemished cycle since phosphorus doesn't return to the source from where it is begun, that is, plants. Phosphorus is as of now moderately cycled in develop Amazonian backwoods, thus loss of P during unsettling influence is probably going to fuel any P restriction that may exist. Despite the fact that there is no vaporous type of P that can be lost in critical sums either during a fire or from soils, there might be critical P lost in particulates during flames or in debris that is lost through consequent breeze or water-driven disintegration. The phosphorus cycle process is as per the following, The phosphorus enters the dirt and water through the enduring of rocks. Plants take in these phosphorus particles from the dirt. The phosphates are then moved from plants to herbivores creatures. These herbivores creatures are eaten via carnivores. The phosphates that are consumed by the creatures are come back to the dirt through discharge and from the decay of plants and dead material by organisms. The dead plant materials and other waste items are rotted through the activity of microscopic organisms. The phosphate is discharged out to nature by this procedure. The phosphate in the dirt is drained out or dissolved into water. The water is again used by green growth and plants as supplements.

so we can conclude that the phosphorous cycle as the imperfect cycle.
