What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, involving a series of progressive changes in species composition and community structure.

Front

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 or glacier retreat.

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 ecosystem but left the soil intact, such as after a forest fire.

Front

What is a climax community?

Back

A climax community is a stable and mature ecological community that has reached the final stage of succession, characterized by a diverse array of species.

Front

What role do pioneer species play in succession?

Back

Pioneer species are the first organisms to colonize a barren environment in primary succession, helping to create soil and conditions for other species to thrive.

Front

Give an example of primary succession.

Back

An example of primary succession is the formation of a new ecosystem on a volcanic island after a lava flow cools and solidifies.

Front

Give an example of secondary succession.

Back

An example of secondary succession is the regrowth of a forest after a wildfire has cleared the area.

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 soil is present but the ecosystem has been disturbed.

Front

What factors can influence the rate of succession?

Back

Factors influencing the rate of succession include the type of disturbance, climate, soil quality, and the availability of species.

Front

What is a disturbance in ecological terms?

Back

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