Best Answer - Chosen by Votersit is a natural process in lakes, estuaries.But sometimes human acts accelerate the system.Here excessive amounts of plant nutrients (primarily phosphorus, nitrogen, and carbon) are added to streams and lakes in various ways. Runoff from agricultural fields, field lots, urban lawns, and golf courses is one source of these nutrients. Untreated, or partially-treated, domestic sewage is another major source. Sewage is a particular source of phosphorus to lakes when detergents containe large amounts of phosphates.this leads to the excessive growth, or"blooms", of algae promoted by these phosphates.

these algae cover the entire surface, thus disallows penetration of sunlight to lower parts of the waters and thus the submerged flora get affected.tyey also cause depletion of oxygen and the fishes are killed.Sometimes those fishes are replaced by species more resistant to the new conditions.

Thus eutrophication can be considered a form of pollution because it promotes plant growth, favoring certain species over others and forcing a change in species composition. eventually the entire ecosystem gets afftected....phytoplankton...zooplankton… and small water creatures....the birds feeding on them and all.Doies it afects the biodiversity to a very large extent.Sometimes the algae ecen give out toxins for the animals there.

Surveys showed that 54% of lakes in Asia are eutrophic; in Europe, 53%; in North America, 48%; in South America, 41%; and in Africa, 28%.

What is distinction between eutrophication and artificial eutrophication?

Eutrophication is the natural process of nutrient accumulation in bodies of water, leading to increased plant growth and decreased oxygen levels. Artificial eutrophication is the accelerated accumulation of nutrients in water bodies due to human activities such as agriculture runoff or sewage discharge, causing rapid algae growth and disrupting the ecosystem balance.

How can eutrophication prevent?

we can prevent this by decreasing the use of fertilizer in plants. Excess use of fertilizer can lead to eutrophication.


How many different types of eutrophication are there?

There are two main types of eutrophication: natural eutrophication, which occurs over long periods of time due to natural processes, and anthropogenic eutrophication, which is accelerated by human activities such as excessive nutrient runoff from agriculture and urban areas.


Explain the distinction between eutrophication and artificial eutrophication?

Eutrophication is a natural process where bodies of water become nutrient-rich, promoting excessive plant growth and potentially harming ecosystems. Artificial eutrophication occurs when human activities, such as agriculture runoff or sewage discharge, introduce excess nutrients into water bodies, accelerating the eutrophication process and causing ecological imbalances.


Why is eutrophication bad?

Natural eutrophication isn't as much of a problem as artificial eutrophication. Artificial eutrophication is caused by humans (fertilizer from farms, lawns, gardens, etc. pesticides, herbicides, road chemicals, etc) these chemicals cause eutrophication to happen much faster than it should. If eutrophication happens faster, algal blooms (large floating mats of algae) form. When algal blooms decay, the bacteria that decays it depletes the oxygen in the lake or pond and the fish die of suffocation.

How is eutrophication related with symbiosis?

Eutrophication is not directly related with symbiosis since it involves the excessive amounts of phosphates and nitrates.
