What are the consequences of increased nitrogen and phosphorus into water systems?

Biology

olasank [31]3 years ago

Nitrogen and phosphorus are nutrients that are natural parts of aquatic ecosystems. Nitrogen is also the most abundant element in the air we breathe. Nitrogen and phosphorus support the growth of algae and aquatic plants, which provide food and habitat for fish, shellfish and smaller organisms that live in water.

Answer:

Nitrogen and phosphorus are the essential nutrients that promote the growth of aquatic life forms within water systems ( for instance, they promote the growth of algae).

But when there is too much phosphorus and nitrogen into water systems, it can speed up the process of eutrophication ( increase in the concentration of minerals and nutrients, which enhances the growth of algae, which causes algal blooms). Due to this, dissolved oxygen level is declined as not enough light penetrates in the water body. As a consequence, oxygen is not produced while it is consumed more.

This is hazardous for the other life forms such as fishes that are living in the water as not enough level of oxygen is left in the water system.

What are the right ascension and delineation of the vernal and autumnal equinoxes
valkas [14]

Answer:

Autumnal equinox right ascension = 12 hours; declination = 0°; Sun rises at 90° azimuth and sets at 270° azimuth. December solstice right ascension = 18 hours; declination = -23.5° Sun rises at greater than 90° azimuth and sets at less than 270° azimuth.

¿Qué se puede agregar a un átomo para hacer que un electrón sin valencia en el átomo se convierta temporalmente en un electrón d
NNADVOKAT [17]

Energía.

Explicación:

Generalmente, los electrones giran continuamente en las capas de los átomos. Si estos electrones se encuentran en las capas más externas de un átomo, se denominan electrones de valencia.

Son necesarios para las reacciones químicas de un átomo en particular con otro, a través de sus pérdidas o compartidas.

En los átomos sin valencia, sus capas más externas no tienen electrones en sus capas más externas, tales átomos son estables.

Sin embargo, si se suministra cierta cantidad de energía a dicho átomo, el electrón gana energía y, por lo tanto, se excita.

Por lo tanto, se mueven de niveles de energía más bajos a niveles de energía más altos, y hacen que el átomo sin valencia se convierta en valencia temporalmente, a medida que se mueven hacia la capa más externa.

Answer:

Energy.

Explanation:

Generally, electrons revolves continuously in the shells of  atoms.if these electrons are located in the outer most shells of an atom,they are refereed to as the Valence electrons.

They are needed for chemical reactions of a particular atom with another,through their loses or sharing.

In Non -valence atoms their outermost shells do not have electrons at their outermost shells,such atoms are stable.

However, if  certain quantity of energy is supplied  to  such atom, the electron  gains energy and therefore becomes excited.

They therefore move from lower energy levels to higher energy levels,and makes the non- valence atom becomes valence temporarily, as they move into the outermost shell.

Which of these choices is the primary purpose of the Ramsar Convention
MatroZZZ [7]

Answer:

As the choices are not given, so let's have a look at the Ramsar Convention in general.

The conservation of wetlands is important because the wetlands have a diversified flora and fauna. Destruction of the wetlands would result in many animals and plant species around the world to become extinct or endangered. Hence, this treaty was signed by different countries of the world as an understanding of the current situation of the wet lands.
