Oligotrophic lakes are lakes that have very high oxygen content but have very poor nutrients in it, causing it not to support other living organisms... Our experts can answer your tough homework and study questions. To understand the complexity and confusion associated with the present concept of trophic state, it is necessary to begin with a brief excursion into the history of “trophic state.” We’ll tease apart some of the numerous strands that are woven together into the present concept, and suggest that some of the strands are not as important to the concept as others, and therefore, can and should be discarded. a eutrophic lake has high to excessive nutrient content and vegetation (esp algae), which often results in oxygen depletion and lack of animal life. Terms. This lakes or water bodies support aquaticspecies that require well-oxygenated, cold waters such as lake trout, char andwhitefish. Oligotrophic lakes are characterized by low nutrient values, which limits the lake's ability to support animal life. Find answers and explanations to over 1.2 million textbook exercises.

Oligotrophic lakes generally host very little or no aquatic vegetation and are relatively clear, while eutrophic lakes tend to host large quantities of organisms, including algal blooms. The most similar priority habitats to Oligotrophic and dystrophic lakes are Ponds, Mesotrophic lakes, Eutrophic standing waters and Blanket bog. 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. Einar Naumann,a Swedish limnologist at the University of Lund, Sweden, first developed what we now think o… What are the long term, effects? "Trophic" means nutrition or growth.A eutrophic ("well-nourished") lake has high nutrients and high plant growth. Compare and contrast cultural and natural eutrophication. The water is usually not good for drinking purpose. An oligotrophic lake has low nutrient concentrations and low plant growth. ‘The relationship between gas transfer velocity and wind speed was evaluated at low wind speeds by quantifying the rate of evasion of the deliberate tracer, SF 6, from a small oligotrophic lake.’ ‘In two oligotrophic lakes, calanoid copepods ingested HNF at biomass-specific rates that were 2.2 times higher than those of cladocerans.’ (1). Course Hero is not sponsored or endorsed by any college or university. Consequently, the water remains clear. Mesotrophic lakes fall somewhere in between eutrophic and oligotrophic lakes. Lakes can be categorized according to the increasing productivity as oligotrophic, mesotrophic, eutrophic, and hypereutrophic.Dystrophic lakes used to be classified as oligotrophic due to their low productivity.However, more recent research shows dystrophia can be associated with any of the trophic types. It also intensifies oxygen consumption in the deep layers of the lake as a result of the increased decomposition of dead algae. The oceans can be divided into Atlantic, Pacific, Arctic and Indian. Mesotrophic: Lakes with an intermediate level of productivity are called mesotrophic lakes.These lakes have medium-level nutrients and are usually clear water with submerged aquatic plants. Eutrophic lakes are those waters which have excess amounts of nutrients leading to high primary productivity, which at extremes leads to low light levels and low oxygenation levels. Consequently the water remains clear. Mesotrophic lakes (1). Mesotrophic lake: a lake with intermediate nutrient level and productivity. What is a synergistic effect? Oligotrophic is an antonym of eutrophic. Distinguish between oligotrophic and eutrophic lakes. Oligotrophic: Eutrophic Lakes: These are lakes with fewer nutrients, low productivity, and clear water: These are lakes with high nutrients, high productivity, and dark water: Less phosphate and nitrates: High level of phosphate and nitrates: Biological oxygen demand is quite low. Eutrophic lakes, on the other hand, are productive: net primary production… Lakes are bodies of water that can that is trapped in an area of a basin-like landform. As adjectives the difference between oligotrophic and eutrophic is that oligotrophic is (physiology|of a diet) being deficient in nutrition while eutrophic is (agriculture|of a body of water) being rich in nutrients and minerals and therefore having an excessive growth of algae and thus a diminished oxygen content to the detriment of other organisms. Answer to Distinguish between oligotrophic and eutrophic lakes. Describe the, relationship of DO to BOD. As Mesotrophic lakes sit in the middle of the nutrient spectrum between oligotrophic and eutrophic sites, there is some overlap in the species assemblages found in mesotrophic water bodies and those When comparing the depths, the oceans are deeper than the lakes. What is biomonitoring? What is mountain top removal? The bottoms of the lakes are mostly sandy. 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. Oligotrophic vs Eutrophic Lakes Lake Ecosystem is an example for a lentic ecosystem. They tend to have less surface Lakes can be divided into oligotrophic, mesotrophic and eutrophic. Click to see full answer. Oligotrophic lakes (2). © copyright 2003-2021 Study.com. Privacy Classification of dystrophic lakes. The waters of suchlakes are of high-drinking quality. Oligotrophic lakes are generally very clear, deep, and cold. The water is surrounded by land and the lakes are fed by the waters from the river and rains. mesotrophic lakes include pondweeds Potamogeton spp., especially broad-leaved pondweed species, but also Shetland pondweed Potamogeton rutilus. answer! adj. The amount of decomposable organic matter in bottom sediments is low in oligotrophic lakes and high in eutrophic lakes. What is an indicator species What is biomonitoring An indicator species is an, 4 out of 4 people found this document helpful, What is an indicator species? An aquatic ecosystem with stationary or relatively still water is called lentic ecosystem. (3). What are the current problems in the, Chesapeake? If oligotrophic and eutrophic lakes have dissimilar nutrient sources, N : P may increase or decrease with increased TP. Describe a natural scenario and a human-created scenario under which an oligotrophic lake might be converted to a eutrophic lake. Be able to explain, development upset the natural balance of living and non-living factors, associated with water quality.
