Stable, final stage of succession that can take a hundred or more years to achieve

• adaptation

• pioneer species

• niche

• climax community

Which of the following best describes secondary succession?

• A process that involves only aquatic ecosystems

• A process that occurs in an area with existing soil and previously existing life

• A process that is faster than primary succession

• A process that occurs in an area where no life previously existed

What is the primary difference between primary and secondary succession?

• Primary succession occurs in areas with existing soil, while secondary succession starts on bare rock.

• Primary succession begins on bare rock, while secondary succession occurs in areas with existing soil.

• Primary succession involves only plant species, while secondary succession involves only animal species.

• Primary succession is faster than secondary succession.

In ecological succession, what role do decomposers play?

• They are the first organisms to colonize a barren environment.

• They break down dead organic matter, returning nutrients to the soil.

• They compete with pioneer species for resources.

• They prevent the establishment of new species.

What is the primary role of pioneer species in an ecosystem?

• To compete with existing species for resources

• To establish a climax community

• To modify the environment and make it suitable for other species

• To prevent the growth of invasive species
