Back

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

What is primary succession?

Back

A type of ecological succession that occurs in an environment without soil, such as after a volcanic eruption or glacier retreat.

Front

What is secondary succession?

Back

A type of ecological succession that occurs in an environment that has been disturbed but where soil and some organisms still exist, such as after a forest fire.

Front

How does ecological succession increase biodiversity?

Back

Ecological succession leads to the establishment of a variety of species over time, creating more complex ecosystems and increasing biodiversity.

Front

What is a climax community?

Back

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

Front

What is the main difference between primary and secondary succession?

Back

Primary succession begins without soil, while secondary succession begins with soil already present.

Front

What role do pioneer species play in primary succession?

Back

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

Front

What is a disturbance in the context of ecological succession?

Back

A disturbance is an event that disrupts an ecosystem, such as a fire, flood, or human activity, leading to changes in species composition.

Front

Can ecological succession occur in urban areas?

Back

Yes, ecological succession can occur in urban areas, especially in abandoned lots or areas disturbed by human activity.

Front

What is the significance of biodiversity in an ecosystem?

Back

Biodiversity enhances ecosystem resilience, productivity, and stability, allowing ecosystems to better withstand disturbances.
