What is ecological succession?

Back

The process by which ecosystems change and develop over time, involving a series of stages from pioneer species to a climax community.

Front

What are pioneer species?

Back

The first organisms to colonize an area during succession, often helping to create conditions suitable for other species.

Front

What is a climax community?

Back

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

Front

What role do pioneer species play in succession?

Back

They break down rocks to create soil, allowing other plants to grow.

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.

Front

Give an example of a pioneer species in primary succession.

Back

Mosses and lichens.

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.

Front

What are some factors that can trigger secondary succession?

Back

Natural disasters like fires, floods, or human activities such as farming.

Front

What is a biotic factor?

Back

Living components of an ecosystem, such as plants, animals, and microorganisms.
