Ecological Succession Vocabulary Flashcard

Front

What is aquatic succession?

Back

Aquatic succession is the process of ecological change that occurs in aquatic environments such as ponds, rivers, or lakes.

Front

What is primary succession?

Back

Primary succession is the type of ecological succession that begins in lifeless areas where there is no soil, such as after a volcanic eruption.

Front

What is secondary succession?

Back

Secondary succession is the type of ecological succession that occurs in areas where soil is present but has been disturbed, such as after a forest fire.

Front

What is eutrophication?

Back

Eutrophication is the process by which a body of water becomes overly enriched with nutrients, often due to runoff from fertilizers, leading to excessive growth of algae.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize previously uninhabited or disturbed environments, playing a crucial role in the process of 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, where species composition remains relatively unchanged.

Front

What role do lichens play in succession?

Back

Lichens are often pioneer species that help break down rock and create soil, facilitating the process of primary succession.

Front

How does human activity affect aquatic ecosystems?

Back

Human activities, such as using fertilizers, can lead to eutrophication, which negatively impacts aquatic ecosystems by causing algal blooms and depleting oxygen.

Front

What is the difference between primary and secondary succession?

Back

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

Front

What is an example of a disturbance that can lead to secondary succession?

Back

Examples of disturbances that can lead to secondary succession include forest fires, floods, or human activities like farming.
