Ecological Succession Flashcardizz

Front

What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, involving a series of progressive changes in the species composition and structure of a community.

Front

What are the two main types of ecological succession?

Back

The two main types of ecological succession are primary succession and secondary succession.

Front

What is primary succession?

Back

Primary succession occurs in lifeless areas where soil has not yet formed, such as after a volcanic eruption or glacier retreat.

Front

What is secondary succession?

Back

Secondary succession occurs in areas where a disturbance has destroyed an existing ecosystem but left the soil intact, such as after a wildfire.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize barren environments during the initial stages of ecological succession.

Front

What role do pioneer species play in succession?

Back

Pioneer species help to create soil and improve conditions for other species to establish, facilitating 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.

Front

What typically marks the end of a succession process?

Back

The formation of a climax community typically marks the end of a succession process.

Front

How does soil formation occur during primary succession?

Back

Soil formation during primary succession occurs as pioneer species break down rock and organic matter accumulates.

Front

What is the significance of biodiversity in a climax community?

Back

Biodiversity in a climax community contributes to ecosystem stability, resilience, and the ability to withstand environmental changes.
