EUTROPHICATION VIDEO FLASHCARD

Front

What is Eutrophication?

Back

Eutrophication is the process by which water bodies become enriched with nutrients (like nitrogen and phosphorus), leading to excessive growth of algae and other aquatic plants.

Front

What causes Algal Blooms?

Back

Algal blooms are caused by an excess of nutrients, particularly nitrogen and phosphorus, often from agricultural runoff, sewage discharge, and other sources.

Front

What is the role of sunlight in Algal Blooms?

Back

Algal blooms absorb sunlight, which allows them to photosynthesize and grow rapidly.

Front

Can Eutrophication occur in rivers?

Back

Yes, Eutrophication can occur in both rivers and lakes.

Front

What type of bacteria breaks down dead algae and plants?

Back

Anaerobic bacteria are responsible for breaking down dead algae and plants in water bodies.

Front

What is the primary source of nutrients that lead to Eutrophication?

Back

Common sources include agricultural runoff, sewage, and industrial waste.

Front

Does Eutrophication affect oxygen levels in water?

Back

Yes, Eutrophication can lead to decreased oxygen levels in water, causing hypoxia, which can harm aquatic life.

Front

What is hypoxia?

Back

Hypoxia is a condition in which there is a deficiency of oxygen in a water body, often resulting from Eutrophication.

Front

Is sewage the only cause of Eutrophication?

Back

No, while sewage is a significant contributor, Eutrophication can also be caused by agricultural runoff and other nutrient sources.

Front

Do bacteria use a lot of oxygen during decomposition?

Back

Yes, bacteria consume oxygen while decomposing organic matter, which can lead to lower oxygen levels in water.
