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.

Front

What is primary succession?

Back

Primary succession occurs in an area where no soil exists, such as after a volcanic eruption or glacier retreat.

Front

What is secondary succession?

Back

Secondary succession occurs in areas where soil is present but has been disturbed, such as after a forest fire or flood.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize a barren environment during primary succession, such as lichens and mosses.

Front

How does primary succession differ from secondary succession?

Back

Primary succession starts from bare rock or no soil, while secondary succession begins in areas with existing soil.

Front

What role do pioneer species play in primary succession?

Back

Pioneer species help create soil by breaking down rock and adding organic material as they die and decompose.

Front

What is a climax community?

Back

A climax community is a stable and mature ecosystem that has reached the final stage of succession.

Front

How long does primary succession typically take compared to secondary succession?

Back

Primary succession generally takes longer than secondary succession due to the need to form soil.

Front

What happens to the ecosystem after a forest fire?

Back

After a forest fire, secondary succession occurs, allowing the ecosystem to recover and regenerate.

Front

What are some examples of disturbances that can lead to secondary succession?

Back

Examples include forest fires, hurricanes, floods, and human activities like farming.
