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.

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

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.

What happens if there is too much nitrogen in an aquatic ecosystem?

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.

How does phosphorus affect algae growth?

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 are the effects of nitrates and phosphates in aquatic ecosystems?

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.

Why do nitrogen and phosphorus promote algae growth?

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.

Why is too much nitrogen and phosphorus bad for the environment?

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.

Basin and Mountain Range Topography

In geology, a basin is defined as a boundary area where the rocks within the boundary slope inward toward the center. In contrast, a mountain range is a series of mountains or hills that form a series of lands higher than the surrounding area.

Basin and Range Province, a dry geographic state that occupies most of the western and southwestern United States. The region includes much of Nevada, the western half of Utah, southeastern California, and southern Arizona, and extends to northwestern Mexico.

How might Texas’ aquatic species differ from species in other states, for example in Oregon, Michigan, or New York?

weeeeeb [17]

The Texas species differ from those in Michigan, Oregon, and New York because they have physical adaptations for a different (warmer) environment.

<h3>How are aquatic species in Texas different from aquatic species in Oregon, Michigan, and New York?</h3>

The different species of animals that exist around the world are the result of long physical and chemical processes of adaptation to the environment and the climatic, biotic and abiotic conditions of a place. From the above, it can be inferred that species from two different points on the planet (for example: Michigan, Oregon and New York and Texas) have different physical and biological conditions as a result of their adaptation processes.

In particular, the aquatic species of Texas are characterized by having greater adaptability to warm waters due to the latitudinal location of this state. On the other hand, fish from Michigan, Oregon, and New York are more likely to survive in cooler waters because they are closer to the North Pole. Additionally, these species are in regions where the seasons change throughout the year, so their bodies must be adapted to these conditions.

Where is the closest group of asteroids to the sun, and what do we call this region?

faltersainse [42]

Answer:

The closest group of asteroids to our Sun is called the Asteroid Belt. It is 329 million to 478.7 million km away from our Sun.

Explanation:

No other group of asteroids is closer than this one. You can find the Asteroid Belt between the orbits of Jupiter and Mars. Half of the mass of these asteroids is from asteroids Ceres, Vesta, Pallas, and Hygiea.
