Ecological Succession

Front

What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, leading to a more stable community.

Front

What is primary succession?

Back

Primary succession is the type of ecological succession 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 type of ecological succession that occurs in areas where a disturbance has destroyed an existing ecosystem but left the soil intact, like after a forest fire.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize barren environments, helping to create soil and establish a new ecosystem.

Front

Why does primary succession take longer than secondary succession?

Back

Primary succession takes longer because it starts from bare rock and must build soil, while secondary succession starts with existing soil.

Front

What is a climax community?

Back

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

Front

What role do lichens play in primary succession?

Back

Lichens help break down rocks and contribute to soil formation, making them essential in primary succession.

Front

What happens after a forest fire?

Back

After a forest fire, secondary succession occurs, where the ecosystem begins to recover and regrow.

Front

What is the first step in primary succession?

Back

The first step in primary succession is the colonization of bare rock by pioneer species like lichens.

Front

What is an example of a pioneer species?

Back

An example of a pioneer species is lichen, which can grow on bare rock.
