Phosphorus is an essential nutrient for plant growth. Excessive amounts of pollution can cause algal blooms, assuming all other nutrients and conditions are right. Algal blooms pose several threats to freshwater ecosystems. During the growing season, algae grows very rapidly and absorbs large amounts of light. This prevents light from reaching the benthic zone (bottom of the body of water--soil and sediment) which can pose a problem for submerged aquatic vegetation which oxygenates the water column. At the end of the growing season, the algal bloom dies, sending billions of tiny organisms to the bottom. There they are broken down by decomposers (bacteria, mostly). These bacteria, just like humans, respirate taking in oxygen and giving off carbon dioxide. With a huge mass of algae to digest, the dissolved oxygen in the water can be reduced severely.
This process described above is called eutrophication, which can lead to:
Hypoxic conditions are when there is a very low amount of dissolved oxygen (D.O.) available for aquatic organisms.
Anoxic conditions are when there is essentially no D.O. available.
Over time these changes would lead to a mostly barren ecosystem, because very few organisms (mostly those that are anaerobic -- don't breath oxygen) can survive in these conditions.
The Chesapeake Bay is a good example of the problems associated with seasonal eutrophication, although it is an estuary, not a freshwater lake - the process is the same.
What else can I help you with?
What is an immediate increase in the amount of algae and other producers that result from a large input of a limiting nutrient?
This is known as an algal bloom. The sudden increase in nutrients like nitrogen or phosphorus can lead to rapid growth of algae, which can create harmful effects in aquatic ecosystems such as depleting oxygen levels and harming other organisms.
What plays a large role in the physical change of matter?
The energy input or removal is a key factor in causing physical changes in matter. When energy is added or taken away from a substance, it can affect the arrangement or movement of its particles, leading to changes such as melting, boiling, freezing, or condensation.
How can oceans and large lakes affect climate and weather?
the large bodies of water evaporate and then it condenses and then perciptates
How do humans affect earthquakes?
Humans can indirectly affect earthquakes through activities like fracking and reservoir-induced seismicity, which can increase the frequency and intensity of seismic events. However, it's important to note that human activities typically contribute to triggering small earthquakes rather than causing large ones. The majority of earthquakes are still driven by natural processes within the Earth's crust.
How do seas affect climate?
The closer you are to a large body of water the more mild the weather is going to be. The farther you are away from the large body of water the more extreme your weather is going to get.
What country produces the most phosphorus?
The United States is the largest producer of phosphorus in the world, followed by China and Morocco. These countries have large reserves of phosphorus rock and extensive mining operations.
How does the release of large amounts of phosphorus by human cause problems?
Igk
How does the release of large amount of phosphorus by humans cause problems?
Igk
What of manure of sea bird contains large amount of phosphorus and nitrates?
urine
Where is phosphorus mined?
Phosphorus is primarily mined in countries like the United States, China, Morocco, and Russia. These countries have large reserves of phosphorus-bearing minerals like phosphate rock, which are extracted through mining processes to produce phosphorus-based products.
What minerals does your body need in large amounts?
Your body needs calcium, chloride, magnesium, phosphorus, potassium, and sodium in large amounts.
How have humans intruded on the phosphorus cycle?
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.
How does the release of large amounts of phosphorus by humans cause problems?
The release of large amounts of phosphorus by humans can lead to eutrophication in water bodies. This excessive phosphorus can stimulate the growth of algae and aquatic plants, leading to algal blooms which can deplete oxygen levels in the water, harming aquatic life. It can also disrupt the balance of ecosystems and biodiversity.
How do humans disrupt the phosphorus cycle?
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.
Is phosphorus pentaiodide a possible compound?
Theoretically PI5 should be formed as PCl5 but practically. due to large atomic size 5 iodine atoms can not attached directly with one phosphorus atom
Why does white phosphorus burn in oxygen?
White phosphorus burns in oxygen to form phosphorus pentoxide, releasing a large amount of energy in the form of heat and light. This reaction is highly exothermic because phosphorus has a high affinity for oxygen, resulting in a rapid and intense combustion process.
What can happen after a lake recives a large input of a limiting nutrient?
After a lake receives a large input of a limiting nutrient such as phosphorus or nitrogen, excessive algal growth can occur. This can lead to algal blooms which deplete oxygen levels in the water, harm aquatic life, and disrupt the ecosystem balance. Additionally, the increased algal growth can lead to a phenomenon known as eutrophication, where the lake becomes overly enriched with nutrients and can become turbid and inhospitable to many organisms.
