Eutrophication process steps

Causes, effects and control Algal bloom in along the coast of Qingdao, eastern China nationalgeographic. It is an abnormal growth of algae, a clear manifestation of a process called eutrophication.

Eutrophication process steps

Arvind Balaraman Eutrophication pronounced you-tro-fi-KAY-shun is a natural process that occurs in an aging lake or pond as that body of water gradually builds up its concentration of plant nutrients.

Cultural or artificial eutrophication occurs when human activity introduces increased amounts of these nutrients, which speed up plant growth and eventually choke the lake of all of its animal life.

In nature, eutrophication is a common phenomenon in freshwater ecosystems and is really a part of the normal aging process of many lakes and ponds. Some never experience it because of a lack of warmth and light, but many do.

Over time, these bodies of freshwater change in terms of how productive or fertile they are. While this is different for each lake or pond, those that are naturally fed rich nutrients from a stream or river or some other natural source are described as "eutrophic," meaning they are nutrient-rich and therefore abundant in plant and animal life.

Eutrophication is not necessarily harmful or bad, and the word itself is often translated from the Greek as meaning "well nourished" or "good food.

Words to Know Algae: Single-celled or multicellular plants or plantlike organisms that contain chlorophyll, thus making their own food by photosynthesis. Algae grow mainly in water.

What is Eutrophication? What are the stages of Eutrophication? | MyTutor

A salt or ester of nitric acid, which is a transparent corrosive liquid composed of nitrogen, hydrogen, and oxygen. A salt or ester of a phosphoric acid, which is any of three acids that are formed when the oxide of phosphorus reacts with water.

Too much of a good thing Natural eutrophication is usually a fairly slow and gradual process, occurring over a period of many centuries. It occurs naturally when for some reason, production and consumption within the lake do not cancel each other out and the lake slowly becomes overfertilized.

While not rare in nature, it does not happen frequently or quickly. However, artificial or human-caused eutrophication has become so common that the word eutrophication by itself has come to mean a very harmful increase and acceleration of nutrients.

It is as if something receives too much fertilizer or has too much of what is a good thing. Humans increase the rate of eutrophication Human activities almost always result in the creation of waste, and many of these waste products often contain nitrates and phosphates.

Nitrates are a compound of nitrogen, and most are produced by bacteria. Phosphates are phosphorous compounds. Both nitrates and phosphates are absorbed by plants and are needed for growth.

However, the human use of detergents and chemical fertilizers has greatly increased the amount of nitrates and phosphates that are washed into our lakes and ponds.

When this occurs in a sufficient quantity, they act like fertilizer for plants and algae and speed up their rate of growth. Algae are a group of plantlike organisms that live in water and can make their own food through photosynthesis using sunlight to make food from simple chemicals.Cultural eutrophication is the process that speeds up natural eutrophication because of human activity.

Due to clearing of land and building of towns and cities, land runoff is accelerated and more nutrients such as phosphates and nitrate are supplied to lakes and rivers, and then to coastal estuaries and bays.

Eutrophication process steps is quite a rare and popular topic for writing an essay, but it certainly is in our database.

Published: Tue, 27 Jun Eutrophication is world-wide environmental issue environmental problems that are related to high concentration nutrients.

It is the process due to increment of algae productivity which affects adversely aquatic life and also human and animal health.

Oct 07,  · Eutrophication may cause competitive release by making abundant a normally limiting nutrient. This process causes shifts in the species composition of ecosystems. For instance, an increase in nitrogen might allow new, competitive species to invade and outcompete original inhabitant Resolved.

Eutrophication is the enrichment of an ecosystem with chemical nutrients, typically compounds containing nitrogen, phosphorus, or both. Eutrophication can be a natural process in lakes, occurring. The cultural eutrophication process consists of a continuous increase in the contribution of nutrients, mainly nitrogen and phosphorus (organic load) until it exceeds the capacity of the water body (i.e.

the capacity of a lake, river or sea to purify itself), triggering structural changes in the waters.
