Is the phosphorus cycle fast?

Is the phosphorus cycle fast?

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.

How does the phosphorus cycle start?

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. Phosphorus in soil can end up in waterways and eventually oceans.

What are the major reservoirs in the phosphorus cycle?

The ocean sediments are therefore by far the greatest reservoirs of phosphorus. In terrestrial ecosystems, much of the available phosphorus moves in a closed cycle between living organisms and the organic debris in the soil. Phosphate (PO43−) is the only important inorganic form involved in this cycle.

What are the major human impacts on the phosphorus cycles?

Humans have had a significant impact on the phosphorus cycle due to a variety of human activities, such as the use of fertilizer, the distribution of food products, and artificial eutrophication. When levels of phosphorus are too high, the overabundance of plant nutrients serves to drive the excessive growth of algae.

What is the long term cycle of phosphorus?

Phosphorus cycles in two ways: a long-term cycle involving the rocks of the Earth’s crust, and a short-term cycle involving living organisms. Living things take in phosphorus from the normal/long rock cycle as phosphorus is found in bedrock in the form of phosphate ions (Ritter, 2001, pg. 68).

Why isn’t the phosphorus cycle considered a global cycle?

The phosphorus cycle differs from other nutrient cycles, because phosphorus has no major atmospheric component to its cycle. Because of the limited availability of phosphorus in the environment, plants have evolved strategies to conserve phosphorus taken up from the soil.

What is the major difference between the phosphorus cycle and the other biogeochemical cycles?

Explain. 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 is the difference between nitrogen cycle and phosphorus cycle?

Nitrogen is mainly used by humans as a fertilizer in farmlands, but its excessive usage can lead to serious problems (such as eutrophication). The phosphorus cycle involves the uptake of phosphorus by organisms. Phosphorus is used by humans as a fertilizer in farmlands and in detergents.

What is the difference between phosphorus and phosphate?

Phosphorus is an element with the symbol “P”. Phosphate is an ion made up of one phosphorus atom and four oxygen atoms, referred to as “PO4”. Because of those oxygen atoms, phosphate weighs 3.066 times as much as phosphorus, so to convert from phosphorus to phosphate, multiply by 3.066, and to go the other way, divide.

What are the side effects of high phosphorus levels?

Symptoms of too much phosphorus These symptoms include joint pain, muscle pain, and muscle weakness. People with high phosphorus levels can also experience itching and red eyes. Symptoms of more severe cases of high phosphorus may include severe constipation, nausea, vomiting, and diarrhea.

What are the side effects of phosphate?

Side Effects

• Confusion.
• convulsions (seizures)
• decrease in amount of urine or in frequency of urination.
• fast, slow, or irregular heartbeat.
• headache or dizziness.
• muscle cramps.
• numbness, tingling, pain, or weakness in hands or feet.
• numbness or tingling around lips.

What is the benefit of phosphate?

Phosphorus works with calcium to help build bones. You need the right amount of both calcium and phosphorus for bone health. Phosphorus also plays an important structural role in nucleic acids and cell membranes. And it’s involved in the body’s energy production.

Is phosphate safe to drink?

The EPA says “The health effects of drinking water with phosphates are not known,” while the FDA considers phosphates as a food additive to be “generally recognized as safe.”

What happens if you drink phosphate?

High phosphorus and calcium levels also lead to dangerous calcium deposits in blood vessels, lungs, eyes, and heart. Over time this can lead to increased risk of heart attack, stroke or death.

Do phosphates affect chlorine?

High phosphates seem to weaken chlorine, as evidenced by low chlorine readings, lowered ORP, and the most visual of all evidence: algae.

What are the toxicity symptoms of phosphorus?

Ingestion of elemental white or yellow phosphorus typically causes severe vomiting and diarrhea, which are both described as “smoking,” “luminescent,” and having a garlic-like odor. Other signs and symptoms of severe poisoning might include dysrhythmias, coma, hypotension, and death.
