Eutrophication & Succession

Front

What is Eutrophication?

Back

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

Front

What is the main cause of Eutrophication?

Back

The main cause of Eutrophication is the runoff of fertilizers, sewage, and other nutrient-rich substances into water bodies.

Front

What happens to oxygen levels during Eutrophication?

Back

Oxygen levels decrease as decomposing algae consume oxygen, leading to dead zones where aquatic life cannot survive.

Front

What is Primary Succession?

Back

Primary Succession is the process of ecological change that occurs in an area where no soil exists, such as after a volcanic eruption.

Front

What is Secondary Succession?

Back

Secondary Succession is the process of ecological change that occurs in an area where a disturbance has destroyed an existing ecosystem but left the soil intact.

Front

Give an example of a natural disturbance that can lead to Secondary Succession.

Back

A forest fire that burns down trees but leaves the soil intact can lead to Secondary Succession.

Front

What role do pioneer species play in succession?

Back

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

Front

What is a climax community?

Back

A climax community is a stable and mature ecological community that has reached the final stage of succession.

Front

How does human activity impact succession?

Back

Human activities, such as deforestation and urbanization, can disrupt natural succession processes and lead to habitat loss.

Front

What is the difference between primary and secondary succession?

Back

Primary succession occurs on bare rock without soil, while secondary succession occurs in areas where soil is present after a disturbance.
