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 species replacements and community changes.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize a barren environment in the process of ecological succession, such as lichens and mosses.

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 community 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.

Front

What role do pioneer species play in primary succession?

Back

Pioneer species help to rebuild soil by breaking down rock and adding organic material, facilitating the growth of other plants.

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 already present after a disturbance.

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, flood, or human activity.

Front

How does biodiversity change during succession?

Back

Biodiversity typically increases during succession as more species colonize and establish themselves in the ecosystem.

Front

What is a seral stage?

Back

A seral stage is an intermediate stage in the process of ecological succession, where different communities of organisms exist before reaching a climax community.
