What is a potential consequence of excess phosphorus and nitrogen in an ecosystem? A dead zone could be produced from depleted oxygen.
What is a potential consequence of excess phosphorus and nitrogen in an ecosystem?
Too much nitrogen and phosphorus in the water causes algae to grow faster than ecosystems can handle. … Large growths of algae are called algal blooms and they can severely reduce or eliminate oxygen in the water, leading to illnesses in fish and the death of large numbers of fish.
What effect does excess phosphorus have on the ecosystem?
Too much phosphorus can cause increased growth of algae and large aquatic plants, which can result in decreased levels of dissolved oxygen– a process called eutrophication. High levels of phosphorus can also lead to algae blooms that produce algal toxins which can be harmful to human and animal health.
What can cause excess levels of nitrogen and phosphorus?
Nitrogen is most likely to come from transportation, industry, agriculture and fertilizer application, while increased phosphorus is more commonly the result of sewage waste, amplified soil erosion and runoff from urban watersheds.
What can excess amounts of nitrogen cause in ecosystems quizlet?
Nitrogen and phosphorus are essential plant nutrients found in aquatic ecosystems, however, in excess amounts, they can cause significant water quality problems.
How does society impact the phosphorus and nitrogen cycle?
Humans affect the phosphorus cycle mainly by the use of fertilizers and raising livestock, especially hogs. Fertilizers and hog waste are high in phosphorus, which makes its way into the soil (where it is necessary in moderate amounts) and, due to runoff, in water.
What are the effects of too much nitrogen in plants?
Too much nitrogen causes plants to become spindly with frail stems. As the foliage continues to grow abundantly, the weak stems become less able to support the plant. Additionally, root growth is stunted, which leads to even less plant support. Eventually, the plant dies because it can no longer support itself.
What is the final consequence that results from high levels of phosphorus that end up in coastal waters?
Phosphorus is an essential element for plant life, but when there is too much of it in water, it can speed up eutrophication (a reduction in dissolved oxygen in water bodies caused by an increase of mineral and organic nutrients) of rivers and lakes.
Why is nitrogen fertilizer bad for the environment?
When nitrogen fertilizer is applied faster than plants can use it, soil bacteria convert it to nitrate. Water-soluble nitrate is flushed out of soils in runoff, where it pollutes groundwater, streams, estuaries, and coastal oceans. In farming communities, it’s not uncommon for nitrate to render drinking wells unusable.
Why is phosphorus a limiting factor in ecosystems?
Because the quantities of phosphorus in soil are generally small, it is often the limiting factor for plant growth. … Phosphates are also limiting factors for plant-growth in marine ecosystems, because they are not very water-soluble. Animals absorb phosphates by eating plants or plant-eating animals.
What happens if you have too much nitrogen in your body?
Uremia is life-threatening because too much nitrogen in the blood is toxic to the body. Symptoms of uremia include confusion, loss of consciousness, low urine production, dry mouth, fatigue, weakness, pale skin or pallor, bleeding problems, rapid heart rate (tachycardia), edema (swelling), and excessive thirst.
What is nitrogen and phosphorus pollution?
Nutrient pollution is the process where too many nutrients, mainly nitrogen and phosphorus, are added to bodies of water and can act like fertilizer, causing excessive growth of algae. … Excessive amounts of nutrients can lead to more serious problems such as low levels of oxygen dissolved in the water.
Why is the use of too much phosphorus rich fertilizers bad for the environment?
Phosphorus moves through soil and plants which eventually animals eat and they use the Phosphorus, and their waste helps return the sulfur to the soil so that other organisms can use it. … Too many Phosphorus-rich fertilizers are bad for the environment because it can cause overgrowth and algal blooms.
