8F: Ecosystem Changes: Succession Quiz

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

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

• Primary succession is faster than secondary succession.

During secondary succession, which of the following processes typically occurs first?

• Growth of mature trees

• Establishment of herbaceous plants

• Soil erosion

• Arrival of pioneer species

In primary succession, what role do lichens play in the ecosystem?

• They decompose organic matter.

• They fix nitrogen in the soil.

• They break down rock to form soil.

• They provide shade for other plants.

Which of the following is a characteristic of a climax community in succession?

• High biodiversity and stability

• Rapid growth and change

• Dominance of pioneer species

• Absence of animal life

In the context of succession, what is meant by the term "pioneer species"?

• Species that are the last to colonize an area

• Species that are the first to colonize a barren environment

• Species that dominate the climax community
