Natural events such as floods and the natural flow of rivers and streams can also wash excess nutrients off the land into the water systems thus causing excessive growth of algal blooms. It is a type of eutrophication that is a result of human activity and is generally caused by the influx of potassium-rich fertilizers into the aqueous body. When eutrophication occurs, a body of water can undergo explosive growth of algae at or near the surface of the water, referred to as algal blooms. How eutrophication, caused by extra nutrients in runoff, can lead to dead zones. d. Dam construction. Algal blooms are highly toxic and once the water reaches the anaerobic conditions, the growth of more toxic bacterial is promoted. It is defined as a measure of the amount of oxygen required by aerobic microorganisms to decompose organic matter in water. When a body of water, such as a river, lake, or pond, aquires a high amount of nutrients, it causes excessive growth of algae. Eutrophication is a form of pollution caused by an increase in the rate of supple organic matter in an ecosystem. Sefala niger M. 0 0. The main cause of eutrophication1 is the large input of It is a type of eutrophication that is a result of human activity and is generally caused by the influx of potassium-rich fertilizers into the aqueous body. Timmy noticed that the water in the pond was crystal clear, and there was very little algae and plant growth. Cultural eutrophication occurs when human water pollution speeds up the aging process by introducing sewage, detergents, fertilizers, and other nutrient sources into the ecosystem. Eutrophication occurs when a body of water – usually a lake or coastal area – has too many nutrients in it, especially nitrogen and phosphorus. Poisoning of the turfgrass caused by excess phosphorous. The latter is the process of providing a water body with nutrients for the aquatic life it supports. Certain industries can produce wastewater, which contribute to eutrophication. On this regard, toxic algal blooms have shut down numerous water supply systems across the globe. Eutrophication is a natural process that results from accumulation of nutrients in lakes or other bodies of water. 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. The bacteria that decompose the dead algae require oxygen, which consumes even more dissolved oxygen in the water, essentially suffocating other organisms. “ 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 ”. Accelerated Masters Degree Programs: How Do They Work? In a young lake the water is cold and clear, supporting little life. just create an account. Abundant plant growth produces an undesirable disturbance to the balance of organisms and the quality of water. As an outcome, the algal blooms limit the amount of dissolved oxygen required for respiration by other animal and plant species in the water. The word “eutrophication” derives from Greek words meaning “well-nourished” and “good food,” as it is an effect of over-nourishment in a body of water. Eutrophication is the natural aging of a lake by biological enrichment of its water. Basically, over-fertilization of water causes algae to grow on the surface. The concentrated animal feeding operations normally discharge the nutrients that find way into rivers, streams, lakes, and oceans where they accumulate in high concentrations thereby plaguing the water bodies by recurring cyanobacterial and algal blooms. Humans also contribute to eutrophication by burning fossil fuels. What primarily causes eutrophication. Nile cabbage, algal blooms, and water hyacinth can spread over an extensive area along the shores and can sometimes float over the entire surface into the land area. The same fertilizers that were intended to enhance crop growth now enhance the growth of algae and aquatic plants. Eutrophication is frequently a result of nutrient pollution such as the release of sewage effluent and run-off from lawn fertilizers into natural waters (rivers or coasts) although it may also occur naturally in situations where nutrients accumulate (e.g. Algae that feed on nutrients grow into unsightly scum on the water surface, decreasing recreational value and clogging water-intake pipes. Agricultural fertilizers are one of the main human causes of eutrophication. credit-by-exam regardless of age or education level. Other causes include sewage and aquaculture, which is the growing or farming of fish, shellfish and aquatic plants. - Definition & Examples, What Is Sustainable Agriculture? How can this be fixed.
