Ecological Succession

Front

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 are the two main types of ecological succession?

Back

The two main types of ecological succession are primary succession and secondary succession.

Front

What is primary succession?

Back

Primary succession 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 occurs in areas where a disturbance has destroyed an existing ecosystem but left the soil intact, such as after a forest fire or flood.

What role do pioneer species play in succession?

Back

Pioneer species are the first organisms to colonize barren environments, helping to create soil and conditions for other species to thrive.

Front

How do lichens contribute to primary succession?

Back

Lichens begin to break down rock to form soil, making it possible for other plants to grow.

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.

Front

What is the significance of disturbances in ecosystems?

Back

Disturbances can reset succession, create new habitats, and increase biodiversity by allowing different species to thrive.

Front

How can fire be beneficial to ecosystems?

Back

Fire can clear out dead vegetation, promote new growth, and help certain species to germinate, thus maintaining ecosystem health.

Front

What is the impact of invasive species on ecological succession?

Back

Invasive species can disrupt natural succession processes by outcompeting native species for resources.
