- algal bloom occurs.
- algae die and are decomposed by bacteria.
- decomposition of algae increase biological oxygen demand.
- oxygen levels decrease.
- fish, macroinvertebrates and other aquatic life dies.
What is the second stage of eutrophication?
2. Algal bloom: The excess nutrients from the chemicals cause the algae in the water to grow at a fast rate and bloom over the surface of a pond/lake.
What are the different types of eutrophication?
Based on the root cause of eutrophication, we can classify eutrophication into two types, namely anthropogenic eutrophication and natural eutrophication.
What are 4/5 Possible causes of eutrophication?
Causes of Eutrophication
- Fertilizers (nitrates and phosphates) Eutrophication is predominantly caused by human actions due to their dependence on using nitrate and phosphate fertilizers. …
- Concentrated Animal Feeding Operations. …
- Direct Sewage Discharge and Industrial Waste into Water Bodies. …
- Aquiculture. …
- Natural Events.
What is eutrophication explain the causes and steps of eutrophication?
Harmful algal blooms, dead zones, and fish kills are the results of a process called eutrophication — which occurs when the environment becomes enriched with nutrients, increasing the amount of plant and algae growth to estuaries and coastal waters.
What is the first step in the process of eutrophication quizlet?
What is the 1st step of Eutrophication? Fertilizers & animals wastes enter lake or pond. You just studied 7 terms!
What is the first step in the eutrophication?
Eutrophication occurs in 4 simple steps: EXCESS NUTRIENTS: First, farmers apply fertilizer to the soil. Then, excess nutrients run off from the field into the water. ALGAE BLOOM: Next, the fertilizer rich in nitrate and phosphate spark the overgrowth of algae in water bodies.
How many types of eutrophication are there?
two types Based on the root cause of eutrophication, we can classify eutrophication into two types, namely anthropogenic eutrophication and natural eutrophication.
What are 2 types of eutrophication?
Based on the root cause of eutrophication, we can classify eutrophication into two types, namely anthropogenic eutrophication and natural eutrophication.
What are the causes and stages of eutrophication?
Eutrophication occurs in 4 simple steps:
- EXCESS NUTRIENTS: First, farmers apply fertilizer to the soil. …
- ALGAE BLOOM: Next, the fertilizer rich in nitrate and phosphate spark the overgrowth of algae in water bodies.
- OXYGEN DEPLETION: When algae forms, it blocks sunlight from entering water and uses up oxygen.
What are the 4 effects of eutrophication?
The known consequences of cultural eutrophication include blooms of blue-green algae (i.e., cyanobacteria, Figure 2), tainted drinking water supplies, degradation of recreational opportunities, and hypoxia.
What are the various causes of eutrophication?

What causes eutrophication to occur?
Eutrophication is predominantly caused by human actions due to their dependence on using nitrate and phosphate fertilizers. Agricultural practices and the use of fertilizers on lawns, golf courses and other fields contribute to phosphate and nitrate nutrient accumulation.
Which of the following contributes to the process of eutrophication?
The most common nutrients causing eutrophication are nitrogen N and phosphorus P. The main source of nitrogen pollutants is run-off from agricultural land, whereas most phosphorus pollution comes from households and industry, including phosphorus-based detergents.
What are the 2 types of eutrophication?
Based on the root cause of eutrophication, we can classify eutrophication into two types, namely anthropogenic eutrophication and natural eutrophication.
What is eutrophication and types?
Eutrophication refers to an increase in nutrients, especially nitrogen and phosphorus, which leads to an explosive increase in the growth of algae, called algal blooms. Eutrophication also includes the increased input of sedimentary material. There are two types of eutrophication: natural and cultural.
What are the two major causes of eutrophication?
The most common nutrients causing eutrophication are nitrogen N and phosphorus P. The main source of nitrogen pollutants is run-off from agricultural land, whereas most phosphorus pollution comes from households and industry, including phosphorus-based detergents.
What are 3 sources of the contaminants that cause eutrophication?

What is eutrophication and it type?
Eutrophication is the process in which a water body becomes overly enriched with nutrients, leading to plentiful growth of simple plant life. The excessive growth (or bloom) of algae and plankton in a water body are indicators of this process.
What is eutrophication in detail?
Harmful algal blooms, dead zones, and fish kills are the results of a process called eutrophication — which occurs when the environment becomes enriched with nutrients, increasing the amount of plant and algae growth to estuaries and coastal waters.
What is step #1 in eutrophication?
Eutrophication occurs in 4 simple steps: EXCESS NUTRIENTS: First, farmers apply fertilizer to the soil. Then, excess nutrients run off from the field into the water. ALGAE BLOOM: Next, the fertilizer rich in nitrate and phosphate spark the overgrowth of algae in water bodies.
