    Eutrophication

    • 1102 Words
    • 3 Pages

    Eutrophication comes from the Greek word "eutrophos" meaning well-nourished. In other words, this natural process found in water occurs as a result of additional rich nutrients forming a flourish in plant production. At this moment in time, eutrophication is causing worldwide devastation to not only aquatic life, but the fishing industry. The release of nutrients into fresh water lakes, rivers and reservoirs leads to excessive growth of three different plant species: a) Open water algae (phytoplankton)

    What is eutrophication? Eutrophication is, in the simplest terms, too much of a good thing. 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 in 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

    Eutrophication is defined as excessive richness of nutrients in a lake or other body of water. It is frequently due to runoff from the land, which causes a dense growth of plant life and, a subsequent death of animal life from a concentration lack of oxygen resulting from the oxidation of organic matter (Chrislock et al., 2013). Eutrophic systems can be observed to have shallow waters, high concentrations of nutrients, high productivity, and high oxygen usage. This process of eutrophication occurs

    Ecosystems can be defined as a complex biological community of interacting organisms and their physical environment (Google, 2018). Eutrophication is a process by which water gains high concentrations of nutrients. Typically, the nutrients consist mainly of phosphate and nitrate which tend to promote large quantities of algae growth. The death and decomposition of algae, organic matter and other decomposing organisms deprive the water of oxygen, thus causing significant death of marine life like

    Eutrophication is the ecosystem response to an excessive richness of nutrients in an aquatic ecosystem. Normally eutrophication is a non-harmful, natural process that occurs when a body of water is aging. The natural cause of eutrophication is the run-off of nutrients from nearby soil and erosion. However a different type of eutrophication is human-caused which accelerates the aging process and creates environmental issues. When there is an excessive richness of nutrients in a body of water,

    Eutrophication in the Gulf of Mexico Introduction Even though the Midwestern United States produces the majority of the country’s agriculture to date, this immense agricultural activity in the Midwest region has not only degraded the land itself but also the water in the regional rivers and tributaries, which is all interconnected in the network known as the Mississippi-Atchafalaya River Basin (also referred to as MARB). The MARB (Figure 1) covers an extensive 1,245,000 square miles and drains out

    Eutrophication is the over-enrichment of nutrients in a body of water, due to runoff from the land, which causes a condensed growth of plant life. This occurrence also causes death of animal life from lack of oxygen (Oxford Dictionary, 2016). The nutrients that become overly abundant are nitrogen phosphorus which causes problems in most natural environments. The problems caused by this nutrient are hypoxia and harmful algae blooms. Hypoxia is the depletion of oxygen. If oxygen is taken out of the

    Introduction What is your topic/issue within that topic? Eutrophication is a concern in the Chesapeake Bay. Eutrophication is caused by excessive amounts of nutrients. Excessive nutrients in the bay have negative effects on the bay's ecosystem. The extra nutrients make the environment unbalanced. The extra nutrients cause a chain reaction that eventually kills most of the organisms in that area. This is what is known as a dead zone. What is your personal interest in the topic? This topic is interesting

Eutrophication arises from the oversupply of nutrients, which induces explosive growth of plants and algae which, when such organisms die, they consume the oxygen in the body of water, thereby creating the state of hypoxia (deficiency in the amount of oxygen reaching the tissues) Mechanism

    Introduction Eutrophication is a widespread matter of concern affecting estuaries and other coastal ecosystems, and detrimental to coastal and marine species (Gray, Wu & Or 2002; Bricker et al. 2008). Gray, Wu and Or (2002) describe the eutrophication process as an increase in different nutrient levels resulting in creation of both dissolved and particles of organic substance which ultimately leads to decrease in level of oxygen concentrations due to decaying or degeneration of those organic substances

    Eutrophication is the reaction resulting from the addition of harmful substances to aquatic ecosystems. Eutrophication causes decreased biodiversity, changes in species composition and dominance dissolved oxygen depletion and problems in water treatments. Eutrophication is currently happening to many of the Canadian Lakes including Lake Winnipeg. Since 1969, it has been observed that Cyanobacteria (blue-green algae) has been the reason for the 90% hike in the algal blooms.Cyanobacteria causes a smelly

This process of the fertilizers getting into the water is called eutrophication, and it also darkens and clouds all the water, not to mention causing harsh odor problems in the water. The darkened water reduces the algae and plants execution of photosynthesis, which means less oxygen, is produced. Finally, when the algae

This in turn causes algae to overgrow in the river (called eutrophication), this turns that water green. When all of this algae dies bacteria break them up using all of the oxygen in the river killing all of the other organisms (http://www.lenntech.com/rivers-pollution-quality.htm).

This is a valid aim as the results could be used as a method of deterring and removing eutrophication in bodies of water where other methods may not be suitable. It is expected that the higher levels of nitrates will cause duckweed colonies in a body of water to grow in population at the same time lowering levels of nitrates in the water. If

    was ecologically balanced, but we tipped the balance slightly and wrecked havoc upon the environment. It has been noted to occur since the 1950’s and is ongoing. The reason that this dead zone occurs is because of a phenomenon known as eutrophication. Eutrophication is when there is an excessive amount of nutrients in a body of water and it causes an abundance of plants to grow. In this case the nearby farms had been using nitrogen in their fertilizers. The nitrogen got carried into the ocean through
