Ecological Succession (Primary and Secondary)

Front

What is Ecological Succession?

Back

The process by which ecosystems change and develop over time, involving a series of stages leading to a stable community.

Front

What are the two main types of ecological succession?

Back

Primary Succession and Secondary Succession.

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 or glacier retreat.

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, such as after a forest fire.

Front

What is a Climax Community?

Back

The final, stable community in an ecological succession that remains relatively unchanged until disrupted by an event.

Front

What are Pioneer Species?

Back

The first species to colonize previously disrupted or damaged ecosystems, often leading to the establishment of a new community.

Front

Give an example of a Pioneer Species.

Back

Lichens and mosses are common examples of pioneer species that can grow on bare rock.

Front

What is the role of Pioneer Species in Primary Succession?

Back

They help to create soil by breaking down rock and accumulating organic material.

Front

What is the difference between Primary and Secondary Succession in terms of time?

Back

Secondary Succession generally occurs faster than Primary Succession because soil and some organisms are already present.

Front

What is an example of an area that undergoes Secondary Succession?

Back

A forest recovering after a wildfire.
