practice flashcard Ecological Succession

Front

What is ecological succession?

Back

The process in which a community changes through time, leading to the development of a stable ecosystem.

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 community but left the soil intact, such as after a forest fire.

Front

What role do lichens play in primary succession?

Back

Lichens help to break down rocks to create soil, making it possible for other plants to grow.

Front

What is a pioneer species?

Back

The first species to colonize previously disrupted or damaged ecosystems, often initiating the process of ecological succession.

Front

Give an example of a pioneer species in primary succession.

Back

Lichens and mosses are common pioneer species that can grow on bare rock.

Front

What is the order of species appearance in secondary succession?

Back

Typically, grasses and small plants appear first, followed by shrubs and then trees.

Front

How does ecological succession contribute to biodiversity?

Back

Ecological succession increases biodiversity by creating new habitats and resources for different species over time.

Front

What is the difference between primary and secondary succession?

Back

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

Front

What is a climax community?

Back

A stable and mature community that undergoes little change in species composition, typically reached at the end of ecological succession.
