Eutrophication Essay -- Geology

What is eutrophication? Eutrophication is, in the simplest terms, likewise much of a good thing. It occurs when too many nutrients ar deposited into a body of water, throwing off the established balance of production and use of goods and services of primitive fertilizer emergence. Eutrophication can take place in ponds, lakes, rivers, and oceans. At first, the soak of nutrients in the body of water encourages plant growth. However, soon this excess of organic fertilizer stuff and nonsense uses up most of the on hand(predicate) oxygen in the water, taking it forth from the other plants and animals. These other organisms can no longer pass with much(prenominal) depleted oxygen levels and die off, creating what is referred to sometimes as a light zone, devoid of life. Below is a table of the several(predicate) trophic states, or levels of organic matter in relation to available oxygen, that a body of water traverses on its way to becoming a departed zone. TROPHIC STATESOligotrophic Clear waters with little organic matter or sediment and minimum biologic activity.Mesotrophic Waters with more nutrients, and therefore, more biological productivity.Eutrophic Waters extremely rich in nutrients, with risque biological productivity. Some species may be choked out.Hypereutrophic Murky, highly racy waters, immediate to the wetland status. Many clearwater species cannot survive.Dystrophic Low in nutrients, highly colored with change state humic organic material. (Not necessarily a part of the natural trophic progression.) confirm to meridian What causes eutrophication? Eutrophication of bodies of water is a naturally occurring phenomenon.

It occurs when too many nutrients are deposited into a body of water, throwing off the established balance of production and consumption of organic matter. Eutrophication can take place i n ponds, lakes, rivers, and oceans. At first, the overload of nutrients in the body of water encourages plant growth. However, soon this excess of organic material uses up most of the available oxygen in the water, taking it away from the other plants and animals. These other organisms can no longer survive with such depleted oxygen levels and die off, creating what is referred to sometimes as a dead zone, devoid of life. Below is a table of the different trophic states, or levels of organic matter in relation to available oxygen, that a body of water traverses on its way to becoming a dead zone. TROPHIC STATESOligotrophic Clear waters with little organic matter or sediment and minimum biological activity.Mesotrophic Waters with more nutrients, and therefore, more biological productivity.Eutrophic Waters extremely rich in nutrients, with high biological productivity. Some species may be choked out.Hypereutrophic Murky, highly productive waters, closest to the wetland status.
