Eutrophication: 20 Questions

Front

What is eutrophication?

Back

Eutrophication is the process by which a body of water becomes overly enriched with nutrients, leading to excessive growth of algae and depletion of oxygen.

Front

What causes eutrophication?

Back

Eutrophication is primarily caused by runoff from fertilizers, sewage, and detergents that contain high levels of nutrients like nitrogen and phosphorus.

Front

What is an algal bloom?

Back

An algal bloom is a rapid increase in the population of algae in water bodies, often resulting from eutrophication.

Front

How does eutrophication affect oxygen levels in water?

Back

Eutrophication leads to decreased oxygen levels in water as decomposers break down dead algae, consuming oxygen in the process.

Front

What are the effects of low oxygen levels on aquatic life?

Back

Low oxygen levels can cause the death of fish and other aquatic organisms, leading to a decline in biodiversity.

Front

What role do decomposers play in eutrophication?

Back

Decomposers break down dead organic matter, consuming oxygen and contributing to the depletion of oxygen levels in eutrophic waters.

Front

What is the relationship between population growth and agriculture?

Back

As the population grows, agriculture tends to increase to meet the food demands of the larger population.

Front

What nutrients are primarily responsible for eutrophication?

Back

Nitrogen and phosphorus are the primary nutrients that contribute to eutrophication.

Front

How can eutrophication be prevented?

Back

Eutrophication can be prevented by reducing nutrient runoff through better agricultural practices, wastewater treatment, and controlling stormwater.

Front

What is the impact of eutrophication on water quality?

Back

Eutrophication negatively impacts water quality by causing algal blooms, which can produce toxins and reduce clarity.
