what is eutrophication in biology

Eutrophication (from Greek eutrophos, "well-nourished"), dystrophication or hypertrophication, is the process by which a body of water becomes overly enriched with minerals and nutrients which induce excessive growth of algae. Eutrophication is mainly caused by two nutrients, phosphorus and nitrogen.These are normally brought to aquatic ecosystems as runoff from fertilized agricultural areas, erosion from river banks, river beds, clearing of land (deforestation), or sewage that ends up in aquatic environments. “ Eutrophication is an enrichment of water by nutrient salts that causes structural changes to the ecosystem such as: increased production of algae and aquatic plants, depletion of fish species, general deterioration of water quality and other effects that reduce and preclude use ”. It happens after farmers spread nitrogen based fertilizers on the fields. Ring in the new year with a Britannica Membership, This article was most recently revised and updated by, https://www.britannica.com/science/eutrophication. Eutrophication is a process which occurs due to the excessive release of nutrients into water bodies. Oligotrophic waters are poorly fed by the nutrients nitrogen and phosphorus and have low concentrations of these constituents. Historically, aquatic systems have been classified as oligotrophic or eutrophic. This is particularly true of stratified systems such as, for instance, lakes during summer when concentrations of molecular oxygen may reach levels of less than about one milligram per litre—a threshold for various biological and chemical processes. Updates? On the basis of nutrition status and productivity, water systems are classified as; You may want to see this related question on eutrophication and its causes in the Biology section. Learn eutrophication biology with free interactive flashcards. There are more species of insects than any other species combined. The plant deplete the oxygen content of water during night. These fertilizers are the perfect type of nutrients to feed hungry algae and plankton, and when it rains, these fertilizers run off into lakes, streams, rivers and oceans. Eutrophication can also produce carbon dioxide, which lowers the PH of the water , also harming the aquatic animals. This causes a dense growth of plant life in the water body. Definition of eutrophication. Cultural eutrophication has had dramatic consequences on freshwater resources, fisheries, and recreational bodies of water and is one of the leading causes of aquatic ecosystem degradation. Eutrophication is derived from the Greek word ‘eutrophos’ that means well-nourished or enriched Eutrophication is the excessive presence of nutrients like nitrate and phosphate in a lake or other water bodies, which causes a dense growth of plant life. Definition of eutrophication : the process by which a body of water becomes enriched in dissolved nutrients (such as phosphates) that stimulate the growth of aquatic plant life usually resulting in the depletion of dissolved oxygen Eutrophication Has Greek Roots Example Sentences Learn More about eutrophication Eutrophication Has Greek Roots Harmful algal blooms , dead zones , and fish kills are the results of a process called eutrophication — which occurs when the environment becomes enriched with nutrients, increasing the amount of plant and algae growth to estuaries and coastal waters. The productivity or fertility of such an ecosystem naturally increases as the amount of organic material that can be broken down into nutrients increases. Meaning of Eutrophication: Inorganic nitrates and phosphates in excess amount stimulate excessive plant growth in lake and reservoir. Eutrophication is known as one of the reason for water pollution. As there's not enough oxygen , this will result in death of aquatic animals and reduces biodiversity This often results in an overgrowth of algae. Read this tutori.. Dinosaurs represented a major turn in the evolutionary development of organisms on Earth. Increases in global inputs of nitrogenous fertilizers and the mining of phosphate rock have generated increased concern about the effects of eutrophication on enclosed marine ecosystems (Nixon, 1995). Our editors will review what you’ve submitted and determine whether to revise the article. Eutrophication is what a water-based ecosystem does when too many nutrients are added to it. This excess loading of carbon, nitrogen, and phosphorus has led to cultural eutrophication of numerous marine systems, including several polluted eastern U.S. estuaries (e.g., Chesapeake and Delaware bays), the Gulf of Mexico near the Mississippi River, and some estuaries of western Europe (e.g., the Scheldt of Belgium and the Netherlands).

Coastal marine systems also may be affected by this process. When too few nutrients are present, the water is oligotrophic. There is thus low production of organic matter by photosynthesis (equation [6]) in…, …phosphorus, a process known as eutrophication. Eutrophication is usually associated with fertiliser use and run off. This process may result in oxygen depletion of the water body after the bacterial degradation of the algae. Nitrogen from municipal sewage treatment plants and the direct runoff from animal feedlots are serious problems in many places. Eutrophication is a process whereby water bodies, such as lakes, estuaries, or slow-moving streams receive excess nutrients that stimulate excessive plant growth (algae, periphyton attached algae, and nuisance plants weeds). Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. Human activities have significantly increased the amount of nutrients passing into the environment. All living things need specific nutrients to survive. A choking of rivers, lakes and other waterways by excess algae growth which has been stimulated by fertilizers or sewage. Nutrient poisoning affects streams and waterways. "Eutrophication occurs when a body of water receives an excessive nutrient load, particularly phosphorus and nitrogen. The productivity or fertility of such an ecosystem naturally increases as the amount of organic material that can be broken down into nutrients increases. Eutrophication, the gradual increase in the concentration of phosphorus, nitrogen, and other plant nutrients in an aging aquatic ecosystem such as a lake. The content on this website is for information only. The nutrients can be introduced via leaching from soil … On a global scale, the input of organic matter by rivers into the oceans today is twice the input in prehuman times, and the flux of nitrogen, together with that of phosphorus, has more than doubled. Here's an overview in a one minute video. Click to see full answer Thereof, what is eutrophication in biology? The word eutrophication refers to nutrient rich condition of water system. Algal blooming usually caused by runoff of nutrients such as animal waste, fertilizers or raw sewage from the land. Or, the overgrowth of algae and bacteria is choking out other forms of life. Eutrophication A major problem with the use of fertilisers occurs when they are washed off the land by rainwater into rivers and lakes. Eutrophication – the least glamorous topic in IGCSE Biology 4.16 4.17 This is a topic it is easy to overlook in your revision: water pollution by sewage is hardly glamorous and when you combine it with the limited excitement of learning about fertilisers , you don’t have to be a genius to see why many students leave it out. Cultural eutrophication occurs when human water pollution speeds up the aging process by introducing sewage, detergents, fertilizers, and other nutrient sources into the ecosystem. This lesson uses lac operon as an example. Eutrophication is the process in which a water body becomes overly enriched with nutrients, leading to plentiful growth of simple plant life. : the process by which a body of water becomes enriched in dissolved nutrients (such as phosphates) that stimulate the growth of aquatic plant life usually resulting in the depletion of dissolved oxygen.Eutrophication Has Greek Roots Example Sentences Learn More about eutrophication. Eutrophication, or overenrichment with nutrients, is an environmental issue of concern for wetlands, streams, rivers, lakes, and reservoirs worldwide.
