It is decomposed by decomposers
phosphorus, in small quantities, is vital to cellular functions. it effects animals such as: Birds, Humans, Mammals other than humans, reptiles, and amphibians.
Animals are able to obtain phosphorus from plants that they may eat. It is also possible that animals that don't ingest plants can obtain phosphorus from the smaller animals that they may eat that do eat plants.
Animals assimilate phosphorus by the foods that they eat. Phosphorus is in plant cells and is transferred to animals through the plants they eat, in turn carnivores obtain phosphorus from their prey that eat plants.
Eating plants.
Sources of phosphorus in the phosphorus cycle include weathering of rocks, decomposition of organic matter, excretion by organisms, and runoff from fertilized agricultural areas. These sources release phosphorus into the soil, where it can be taken up by plants and eventually re-enter the cycle through consumption by animals and decomposition of organic material.
Animals consume plants which have taken phosphorus out of the soil. They then excrete it in the form of manure and biosolids which returns it to the soil.
Humans are animals
Humans have disrupted the phosphorus cycle by mining large amounts of phosphorus for fertilizers, which can lead to excess runoff into waterways causing eutrophication. Additionally, industrial processes such as detergent production and wastewater discharge can introduce phosphorus into the environment in unnatural ways, further impacting the cycle.
Humans intervene in the phosphorus cycle primarily through mining phosphorus-rich minerals for fertilizer production, which increases the amount of phosphorus entering ecosystems. Excessive use of phosphorus-containing fertilizers in agriculture can lead to surface water pollution through runoff, causing eutrophication in water bodies. Additionally, improper disposal of waste containing phosphorus, such as sewage and detergents, can further disrupt the phosphorus cycle.
Humans are animals.
Humans get the phosphorus they need through their diet by consuming foods like meat, fish, dairy products, nuts, seeds, and whole grains, which are rich sources of phosphorus. Phosphorus is also found naturally in the body's cells and is an essential mineral for various physiological functions.
Humans disrupt the phosphorus cycle mainly through excessive use of phosphorus-based fertilizers in agriculture, leading to nutrient runoff into water bodies. This can cause eutrophication, where excessive phosphorus levels stimulate algal growth and lead to oxygen depletion in aquatic ecosystems. Additionally, deforestation and mining activities can release large amounts of phosphorus into the environment.
