Eutrophication is a general term describing a process in which nutrients accumulate in a body of water, resulting in an increased growth of organisms that may deplete the oxygen in the water. [ 1 ] [ 2 ] Eutrophication may occur naturally or as a result of human actions.
This is the last step in the nitrogen cycle step ... nitrate-enriched groundwater can contribute to eutrophication, a process that leads to high algal population and ...
In the nitrogen cycle, atmospheric nitrogen gas is converted by plants into usable forms such as ammonia and nitrates through the process of nitrogen fixation. These compounds can be used by other organisms, and nitrogen is returned to the atmosphere through denitrification and other processes.
Urban areas also release wastewater and add nitrogen through stormwater runoff. The process of eutrophication, in which an abundance of nutrients encourages the growth of algae and other aquatic plants, can be brought on by elevated nitrogen levels in water. [5]
The process of complete nitrification may occur through separate organisms [1] or entirely within one organism, as in comammox bacteria. The transformation of ammonia to nitrite is usually the rate limiting step of nitrification. Nitrification is an aerobic process performed by small groups of autotrophic bacteria and archaea.
The process of the oversupply of nutrients leading to algae growth and oxygen depletion is called eutrophication. Algal and bacterial blooms have persistently contributed to mass extinctions driven by global warming in the geologic past, such as during the end-Permian extinction driven by Siberian Traps volcanism and the biotic recovery ...
Ted Lange is reflecting on his memories of The Love Boat — and how guest star Gene Kelly didn't turn out to be as "grumpy" as he was led to believe. During the latest episode of Steve Kmetko’s ...
Utilizing a large amount of metabolic energy and the enzyme nitrogenase, some bacteria and cyanobacteria convert atmospheric N 2 to NH 3, a process known as biological nitrogen fixation (BNF). [4] The anthropogenic analogue to BNF is the Haber-Bosch process, in which H 2 is reacted with atmospheric N 2 at high temperatures and pressures to ...
