Eutrophication & Succession

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 are the main nutrients that contribute to eutrophication?

Back

The main nutrients that contribute to eutrophication are nitrogen and phosphorus.

Front

What is a dead zone in aquatic environments?

Back

A dead zone is an area in a body of water where oxygen levels are so low that most marine life cannot survive.

Front

How does algae growth affect aquatic ecosystems?

Back

Rapid algae growth can block sunlight from reaching underwater plants, disrupt food chains, and lead to oxygen depletion when the algae die and decompose.

Front

What is the role of fertilizers in eutrophication?

Back

Fertilizers contain high levels of nitrogen and phosphorus, which can run off into water bodies and promote eutrophication.

Front

What happens to oxygen levels during eutrophication?

Back

Oxygen levels decrease as algae die and decompose, leading to hypoxic conditions that can harm aquatic life.

Front

Can eutrophication occur in rivers?

Back

TRUE, eutrophication can occur in both rivers and lakes.

Front

What is the term for the process of algae covering the surface of water?

Back

This process is often referred to as algal bloom.

Front

What are the consequences of algal blooms?

Back

Consequences include reduced water quality, fish kills, and harmful effects on drinking water.

Front

What is succession in ecological terms?

Back

Succession is the process by which ecosystems change and develop over time, often following a disturbance.
