What is Primary Succession?

Back

Primary Succession is 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

Secondary Succession is 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.

Pioneer Species are the first organisms to colonize previously disrupted or damaged ecosystems, often including lichens and mosses.

Front

What is a Climax Community?

Back

A Climax Community is a stable, mature ecological community that has reached a steady state through the process of succession.

Give an example of a Pioneer Species in Primary Succession.

Back

Mosses and Lichens are examples of Pioneer Species that can grow on bare rock in primary succession.

Front

What role do Pioneer Species play in an ecosystem?

Back

Pioneer Species help to create soil and conditions that allow other species to establish and grow, facilitating ecological succession.

Front

What is the difference between Primary and Secondary Succession?

Back

Primary Succession occurs in lifeless areas without soil, while Secondary Succession occurs in areas where a disturbance has happened but soil remains.

Front

What is a disturbance in an ecological context?

Back

A disturbance is an event that significantly alters the structure of an ecosystem, such as fire, flood, or human activity.

Front

What is the first stage of Secondary Succession?

Back

The first stage of Secondary Succession typically involves the rapid growth of grasses and herbaceous plants.
