Natural eutrophication: The natural addition of excessive nutritional substances in a lake or body of water. eutrophication process beyond the rate associated with the natural process (e.g. From the time a lake is created through glacial action, the aging or filling in process begins. Lake aging is the natural process by which a lake fills in over geologic time with erosional materials carried in by tributary streams, with materials deposited directly from the atmosphere, and with materials produced within the lake itself. eutrophication depends only on the local geology and natural features of the catchment. a. ©2021 eNotes.com, Inc. All Rights Reserved. Cultural or artificial eutrophication occurs when human activity introduces increased amounts of these nutrients, which speed up plant growth and eventually choke the lake of all of its animal life. Cultural eutrophication is when a flux of excess nutrients from human activity are added into a local run-off which in turns speeds up the natural eutrophication. The excessive algal growth came back three years later, causing problems to 500,000 residents of Toledo whose tap water was rendered hazardous to their health, when a toxic compound from the algae made its way into the city water supply. Although this is a slow process, it may be increased with the addition of human pollution which is called “Cultural Eutrophication “. Eutrophication (pronounced you-tro-fi-KAY-shun) is a natural process that occurs in an aging lake or pond as that body of water gradually builds up its concentration of plant nutrients. Due to clearing of land and building of towns and cities, land runoff is accelerated and more nutrients such as phosphates and nitrate are supplied to lakes and rivers, and then to coastal estuaries and bays.

The difference between natural eutrophication and cultural eutrophication is that cultural eutrophication is caused by human beings. All rights reserved. This is caused by human activity, this problem became apparent once the green revolution and industrial revolution began in the last century. Eutrophication is a process whereby there is an overabundance of nutrients in a water body. Cultural eutrophication causes major changes in the water with the addition of excess amount of nutrients; mainly phosphate and nitrates. © copyright 2003-2021 Study.com.

Cultural eutrophication happens when the amount of nutrients in the water and/or the water temperature are changed due to human activity, and the eutrophication process begins to run at high speed. Nitrogenous compounds in fertilizers are major contributors to waterway eutrophication and GHG emissions, and the Haber–Bosch process for making fertilizers is very energy-intensive. This is termed cultural eutrophication and in many parts of the world has resulted in a number of deleterious effects to ecosystems. As land is developed, the natural habitat is altered and phosphorus is no longer held in the soil but is washed into lakes. Natural. During this process an oligotrophic lake is converted into an eutrophic lake. It is simply the increase in concentration of a substance in a food chain, not an organism. It involves the accumulation of  nutrients in the water and the bottom sediments. It is also common when sewage, either treated or untreated, enters a body of water, and when the outflow from septic tanks enters a stream or pond. Cultural Eutrophication.

Eutrophication is mainly divided into natural and cultural Eutrophication. Top subjects are Science, Social Sciences, and Literature. As seen in Figure 2, cultural eutrophication is caused by human land use, including agriculture and residential or industrial developments. It permits the production of phytoplankton, algal blooms and aquatic vegetation that in turn provide ample food for herbivorous zooplankton and fish. What are ten examples of solutions that you might find in your home? When plant growth increases, shed or dead plant material falls to the bottom and as it decays it contributes to even more plant growth. Key Difference – Eutrophication vs Biological Magnification. In natural Eutrophication, a lake is characterized by nutrient enrichment. All water bodies are subject to a natural and slow eutrophication process, which in recent decades has undergone a very rapid progression due to the presence of man and his activities (so called cultural eutrophication). Eutrophication - Natural eutrophication is the process by which lakes gradually age and become more productive. Persistent organic pollutants (POPs) are compounds that biomagnify. Cultural eutrophication is the process that speeds up natural eutrophication because of human activity. This situation leads to the dense growth of plants within that body of water. What is the difference between saturated, unsaturated, and supersaturated? This divided body of water shows the remarkable difference between mesotrophic (moderately enriched) (upper basin) and eutrophic water (lower basin). reducing the use of lawn fertilizers. However, humans, through their various cultural activities, have greatly accelerated this process in thousands of lakes around the globe. The key difference between eutrophication and succession is that eutrophication occurs in an aquatic body whereas succession occurs in any habitat.. Eutrophication and succession are gradual changes that take place in the environment.
