The number of species generally increases as the ecosystem matures.

Front

What is a climax community?

Back

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

Front

What role do disturbances play in ecological succession?

Back

Disturbances like fires or floods can reset succession, allowing new species to establish.

Front

What is the difference between primary and secondary succession?

Back

Primary succession starts with no soil, while secondary succession begins in areas with existing soil.

Front

How does ecological succession affect the environment?

Back

It leads to changes in species composition, nutrient cycling, and habitat structure over time.

Front

What is a common example of primary succession?

Back

The colonization of bare rock after a volcanic eruption.
