Which choice best describes the phosphorus cycle?
EXPLANATION: The phosphorous move in the form of cycle through water, soil, rocks and sediments and organism. Only the trace amount of phosphorus is circulated in the atmosphere at the Earth normal temperature and pressure. The rainfall results in the release of phosphorus from the soil or rocks.
Phosphorus moves in a cycle through rocks, water, soil and sediments and organisms. Over time, rain and weathering cause rocks to release phosphate ions and other minerals. This inorganic phosphate is then distributed in soils and water. Plants take up inorganic phosphate from the soil.
Phosphorus in phosphate in solution is cycled from the soil to producers and then from the producers to consumers. Sediments and Precipitation can go to rocks and minerals can then be transferred to the soil for plants to absorb to then form part of the short term cycle.
“Phosphorus cycle is a biogeochemical process that involves the movement of phosphorus through the lithosphere, hydrosphere and biosphere.”
Phosphorus moves slowly from deposits on land and in sediments, to living organisms, and than much more slowly back into the soil and water sediment. The phosphorus cycle is the slowest one of the matter cycles that are described here.
The phosphorus cycle is the process by which phosphorus moves through the lithosphere, hydrosphere, and biosphere. Phosphorus is essential for plant and animal growth, as well as the health of microbes inhabiting the soil, but is gradually depleted from the soil over time.
Phosphorus is needed for the growth, maintenance, and repair of all tissues and cells, and for the production of the genetic building blocks, DNA and RNA. Phosphorus is also needed to help balance and use other vitamins and minerals, including vitamin D, iodine, magnesium, and zinc.

- erosion and weathering.
- runoff of hydrogencarbonate.
- dissolved calcium ions in the surface layer.
- uptake.
- death and decay.
- upwelling.
Phosphorus is therefore the main limiting factor for plant growth in most soils and aquatic ecosystems. Animals obtain phosphorus by eating plants and/or herbivores. Dead organisms and animal wastes return phosphorus to the soil, to streams, and eventually to ocean floors as rock deposits.
The phosphorus cycle is different from other biogeochemical cycles because atmosphere is not important in the transfer or movement of phosphorus. Also, phosphorous compounds on Earth are normally solids of varying temperatures and pressures.
What are the stages of phosphorus cycle?
The global phosphorus cycle has four major components: (i) tectonic uplift and exposure of phosphorus-bearing rocks to the forces of weathering; (ii) physical erosion and chemical weathering of rocks producing soils and providing dissolved and particulate phosphorus to rivers; (iii) riverine transport of phosphorus to ...
Key points. Phosphorus is an essential nutrient found in the macromolecules of humans and other organisms, including DNAstart text, D, N, A, end text. The phosphorus cycle is slow.
The largest reservoir of phosphorus is in sedimentary rock. It is in these rocks where the phosphorus cycle begins. When it rains, phosphates are removed from the rocks (via weathering) and are distributed throughout both soils and water. Plants take up the phosphate ions from the soil.
The movement of phosphate from the ocean to the land and through the soil is extremely slow, with the average phosphate ion having an oceanic residence time between 20,000 and 100,000 years.
Function for health: its main function is to work with calcuim to harden or ossify bones and teeth. calcium and phosphorus bind to form caluim phosphate, which is the ossifying agent for hard tissue. Phosphorus is also a component of DNA.
Phosphorus is usually considered the “limiting nutrient” in aquatic ecosystems, meaning that the available quantity of this nutrient controls the pace at which algae and aquatic plants are produced. In appropriate quantities, phosphorus can be used by vegetation and soil microbes for normal growth.
Phosphorus is a mineral found in your bones. Along with calcium, phosphorus is needed for building strong bones, as well as keeping other parts of your body healthy.
The cycle provides all the fresh water available for biological life. the transfer of nitrogen from the atmosphere to the soil, to living organisms, and back to the atmosphere. process of converting nitrogen gas into nitrogen compounds that plants can absorb and use.
Biogeochemical cycles enable the flow of nutrients and energy between living organisms, dead organisms, and the abiotic environment.
Biogeochemical cycles are important because they regulate the elements necessary for life on Earth by cycling them through the biological and physical aspects of the world.
Why is phosphorus so important to living organisms quizlet?
Phosphorus is essential to organisms because it helps forms important molecules like DNA and RNA. The primary productivity of an ecosystem is the rate at which organic matter is created by producers. If a nutrient is in short supply, it will limit an organism's growth.
The phosphorous cycle differs from other nutrient cycles, because it never passes through a gaseous phase like the nitrogen or carbon cycles. Phosphorous levels follow a seasonal pattern in aquatic ecosystems.
Which of the following describes how phosphorus cycles throughout Earth? NOT Phosphorous usually changes form as it cycles from organic to inorganic matter. Maybe: Phosphorus exists as a single element in both living and nonliving things.
Key points. Phosphorus is an essential nutrient found in the macromolecules of humans and other organisms, including DNAstart text, D, N, A, end text. The phosphorus cycle is slow.
As compared to nitrates & other macro elements, decomposers take longer time to decompose any dead biota into phosphates. Decomposers are organisms especially a soil bacterium, fungus, or invertebrate, that decompose organic material. These are the reasons for phosphorus cycle being the slowest biogeochemical cycle.
The phosphorus cycle shows how phosphate ions are transferred through an ecosystem. Phosphate ions are released. As the sedimentary rock erodes, the ions are transferred into soil, sea, lakes and rivers. Plants absorb the phosphate ions through their roots.
