Ecological Succession & Eutrophication

Front

What is Ecological Succession?

Back

The process by which ecosystems change and develop over time, involving a series of stages where different species replace one another.

Front

What is Eutrophication?

Back

A process where water bodies become overly enriched with nutrients, leading to excessive growth of algae and depletion of oxygen.

Front

What are Decomposers?

Back

Organisms, such as bacteria and fungi, that break down dead organic material, releasing nutrients back into the ecosystem.

Front

What is the role of Pioneer Species in succession?

Back

Pioneer species are the first organisms to colonize a barren environment, initiating the process of ecological succession.

Front

What is Primary Succession?

Back

The type of ecological succession that occurs in lifeless areas where soil has not yet formed, such as after a volcanic eruption.

Front

What is Secondary Succession?

Back

The type of ecological succession that occurs in areas where a disturbance has destroyed an existing ecosystem but left the soil intact.

Front

What happens during an Algal Bloom?

Back

Rapid increase in the population of algae in water bodies, often due to excess nutrients, leading to oxygen depletion.

Front

What is the impact of Eutrophication on aquatic life?

Back

It can lead to hypoxia (low oxygen levels), causing fish and other aquatic organisms to die.

Front

What are the first plants to return after a controlled burn?

Back

Grasses and weeds are typically the first to regrow after a controlled burn.

Front

What is the significance of Oxygen in aquatic ecosystems?

Back

Oxygen is essential for the survival of aerobic organisms, including fish and other aquatic life.
