Front

What type of succession occurs after a fire or flood that destroys a habitat but leaves soil intact?

Back

Back

The process by which ecosystems change and develop over time.

Front

What is the difference between primary and secondary succession?

Back

Primary succession occurs on bare rock or soil without previous life, while secondary succession occurs in areas where a disturbance has destroyed an existing ecosystem but left the soil intact.

Front

What role do pioneer species play in primary succession?

Back

Pioneer species are the first organisms to colonize barren environments, initiating the process of ecological succession.

Front

What is the climax community in ecological succession?

Back

A stable and mature community that undergoes little change in species composition.

Front

How do human activities impact ecosystem services?

Back

Human activities can degrade or disrupt ecosystem services, leading to negative effects on biodiversity and human well-being.
