Compare … Hence the oxygen levels of the water are comparatively high. The quantity of biologically useful nutrients like phosphorus, nitrogen, etc., dissolved in the waters of a water body determine the trophic (nutritional) state of the water body. What are some unique factors that contribute to a lake's trophic state?-Rate of nutrient supply -climate-shape of lake basin. Consequently, the water remains clear. The sediments within Toolik Lake in arctic Alaska are characterized by extremely low rates of organic matter sedimentation and unusually high concentrations of iron and manganese. (3). A water body can be oligotrophic, mesotrophic, eutrophic, and hypereutropic: Oligotrophic: An oligotrophic lake or water body is one which has a relatively low productivity due to the low nutrient content in the lake. Similarly, would you rather swim in an oligotrophic lake vs eutrophic lake? Oligotrophic lake: a lake with low productivity, low nutrients and clear water with drinking water quality. Oligotrophs are characterized by slow growth, low rates of metabolism, and generally low population density. Eutrophic lakes are characterized by high nutrient values which allows microorganisms and algae to grow in large numbers which then allows animals that feed on those algae to also be supported. Do different blood types need different diets? Why would an oligotrophic lake be problematic for organisms that reside there? Other articles where Oligotrophic lake is discussed: inland water ecosystem: Biological productivity: Oligotrophic lakes are those that are unproductive: net primary production is only between 50 and 100 milligrams of carbon per square metre per day, nutrients are in poor supply, and secondary production is depressed. Oligotrophic lakes refer to the lakes that have a very less nutrient composition. In oligotrophic environments open water channels normally develop between the stacks, and the channels act as a circulatory system allowing for the dissemination of nutrients and oxygen and removal of metabolic by-products. The waters of such lakes are of high-drinking quality. The water in oligotrophic lakes is also very cold. What are the characteristics of a eutrophic lake? Oligotrophic lakes are typically poor in nutrients and rich in oxygen, while eutrophic lakes are rich in nutrients and poor in oxygen. See more. These environments include deep oceanic sediments, caves, glacial and polar ice, deep subsurface soil, aquifers, ocean waters, and leached soils. Oligotrophic environments include deep oceanic sediments, caves, glacial and polar ice, deep subsurface soil, aquifers, ocean waters, and leached soils. (of a lake) characterized by an abundant accumulation of nutrients that support a dense growth of algae and other organisms, the decay of which depletes the shallow waters of oxygen in summer. Both natural and human-made factors might influence the trophic state of a water body. Effects of climate change on general hydro-ecology in the Arctic . Why speed of light is different in different medium? There are several indicators available to assess the degree of eutrophication: Why do different alcohols have different glasses? The waters of such lakes are of high-drinking quality. Do different liquids evaporate at different rates? Those wishing to attract birds to create a bird sanctuary will prefer a eutrophic lake with plenty of algae to feed the birds. Oligotrophic lakes are usually found in the cold regions of the world where mixing of nutrients is rare and slow due to the low temperatures of the lake waters. Oligotrophic lakes are most common in cold, sparsely developed regions that are underlain by crystalline igneous, granitic bedrock. Andean Patagonian lakes are oligotrophic systems characterized by low dissolved organic carbon (DOC) levels and moderate to high Hg concentration that determine naturally high Hg/DOC ratios and bioavailability. The eutrophic body of water contains high amounts of nutrients. By Oishimaya Sen Nag on April 25 2017 in Environment. Oligotrophic environments are those that offer little to sustain life. The waters of these lakes are usually quite clear due to the limited growth of algae in the lake. Do different cars need different coolant? When these limiting nutrients increase, it triggers higher plant growth in the body of water and a subsequent increase in its trophic level. Why do different elements produce different colors? What's the difference between Koolaburra by UGG and UGG? Copyright 2020 FindAnyAnswer All rights reserved. What type of clothing did Gladiators wear?

The most widely used trophic indices is the Carlson's index. The Great Lakes are a example of glacial lakes. In these lakes the blue-green algae are scarce and water blooms absent, but the remaining features do not fit the conventional scheme. Due to their low algal production, these lakes consequently have very clear waters, with high drinking-water quality. An oligotrophic lake is a lake with low primary productivity, as a result of low nutrient content. Because these lakes have low levels of decomposition, the bottom layer (hypolimnion) will not become depleted of oxygen. (2). Sewage entering the lake intentionally or accidentally, agricultural run-offs from crop-fields, or fertilizers leached into the waters are the different ways in which nutrients are added to a water body due to human activities. The waters of these lakes are usually quite clear due to the limited growth of algae in the lake.
