Ecological Succession

Front

What is ecological succession?

Back

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

What is primary succession?

Back

The type of ecological succession that occurs in an area where no soil exists, such as after a glacier melts or a volcanic eruption.

Front

What is secondary succession?

Back

The type of ecological succession that occurs in areas where a disturbance has destroyed an existing community but soil and some organisms still remain.

Front

What is a pioneer species?

Back

The first species to colonize previously disrupted or damaged ecosystems, often leading to primary succession.

Front

What role do shade-tolerant trees play in succession?

Back

They can grow in low light conditions, allowing them to thrive in the understory of forests and contribute to the development of a mature forest.

Front

What is a climax community?

Back

A stable and mature ecological community that undergoes little or no change in species over time.

Front

What is the difference between primary and secondary succession?

Back

Primary succession starts on bare rock without soil, while secondary succession occurs in areas where soil is present after a disturbance.

Front

What is a disturbance in an ecosystem?

Back

An event that significantly alters the structure or function of an ecosystem, such as fire, flood, or human activity.

Front

What is the significance of biodiversity in ecological succession?

Back

Biodiversity enhances ecosystem resilience, allowing for better recovery from disturbances and more stable communities.

Front

How does soil formation occur during primary succession?

Back

As pioneer species like lichens and mosses grow, they break down rock and contribute organic material, leading to soil development.
