What are the consequences of increased nitrogen and phosphorus into water systems?
larisa86 [58]

Nutrient pollution has impacted many streams, rivers, lakes, bays and coastal waters for the past several decades, resulting in serious environmental and human health issues, and impacting the economy. Too much nitrogen and phosphorus in the water causes algae to grow faster than ecosystems can handle.

<u>What are two sources of increased nitrogen and phosphorus in a river that result from human activity?</u>

Phosphorus (P) and nitrogen (N) are the primary nutrients that in excessive amounts pollute our lakes, streams, and wetlands. Nitrogen is essential to the production of plant and animal tissue. It is used primarily by plants and animals to synthesize protein.

<u>What happens if there is too much nitrogen in an aquatic ecosystem?</u>

Excess nitrogen can harm water bodies. Excess nitrogen can cause overstimulation of growth of aquatic plants and algae. Excessive growth of these organisms, in turn, can clog water intakes, use up dissolved oxygen as they decompose, and block light to deeper waters.

<u>How does phosphorus affect algae growth?</u>

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.

<u>What are the effects of nitrates and phosphates in aquatic ecosystems?</u>

However, at night, dissolved oxygen may decrease to very low levels as a result of large numbers of oxygen consuming bacteria feeding on dead or decaying algae and other plants. Eutrophication – “The process by which a body of water acquires a high concentration of nutrients, especially phosphates and nitrates.

<u>Why do nitrogen and phosphorus promote algae growth?</u>

Nutrients promote and support the growth of algae and Cyanobacteria. The eutrophication (nutrient enrichment) of waterways is considered as a major factor. The main nutrients contributing to eutrophication are phosphorus and nitrogen. ... This phenomenon encourages the growth of algae.

<u>Why is too much nitrogen and phosphorus bad for the environment?</u>

Nutrient pollution is one of America's most widespread, costly and challenging environmental problems, and is caused by excess nitrogen and phosphorus in the air and water. Too much nitrogen and phosphorus in the water causes algae to grow faster than ecosystems can handle.

What is essential for a confederation?
user100 [1]

Answer:

smaller political units maintaining their sovereignty

Explanation:

Confederation is the name given to a country that is a federation, but the states that make up that country maintain their sovereignty, separate from the power of the federal government. In this case, to maintain a confederation it is essential that the smaller political units, the states, maintain their sovereignty. This is different from a federation, because in a federation, states lose sovereignty, transferring it to the federal government.

State how hurricanes are predicted
andrezito [222]
Hurricanes are predicted using a Saffir-Simpson Scale. This scale is used to measure the intensity of hurricane most often than not. However, it may be used to identify a hurricane as well. A hurricane is categorised based on the wind speeds.  

74 - 95 mph --> category 1 
96 -110 mph --> category 2 
111 - 129 mph --> category 3 
130 - 156 mph --> category 4 
157 mph + --> category 5 

Typically, the formation of a hurricane occurs when moist warm air if absorbed from the Atlantic or Pacific Ocean and rises. The moisture will then evaporate further rising and heating until the moist air is twisted and circulation high in the atmosphere.
