Succession Grade 6 Quiz

What is primary succession?

• The process of ecological succession that occurs in an environment that has a high level of biodiversity.

• The process of ecological succession that occurs in an environment that has stable and mature soil.

• The process of ecological succession that occurs in an environment that has never been colonized before.

• The process of ecological succession that occurs in an environment that has been recently disturbed by a natural disaster.

Explain the process of primary succession to David, Rohan, and Abigail in a fun and engaging way!

• Primary succession is the process of ecological succession that occurs in an area where the existing community has been cleared by a natural disaster.

• Primary succession is the process of ecological succession that occurs in an area where no soil is present, such as on bare rock or sand.

• Primary succession is the process of ecological succession that occurs in an area with abundant soil and vegetation.

• Primary succession is the process of ecological succession that occurs in an area where the climate remains stable and unchanged.

What is secondary succession?

• The process of maintaining the existing community in an area

• The process of removing all vegetation from an area

• The process of creating a new community in an area with no existing vegetation

• The process of ecological succession that occurs in an area where an existing community has been partially or completely destroyed.

Describe the stages of secondary succession.

• The stages are rapid, gradual, and immediate

• The stages are early, middle, and late

• The stages are primary, secondary, and tertiary

What is a climax community?

• A community that is constantly changing in species composition

• A community that is in the early stages of development

• A stable, mature community that undergoes little or no change in species over time.

How does a climax community differ from earlier stages of succession?

• What makes a climax community more stable and diverse compared to earlier stages of succession?

• How does a climax community stand out from earlier stages of succession?

• Why is a climax community more stable and diverse than earlier stages of succession?

• What sets a climax community apart from earlier stages of succession?

What are pioneer species?

• The first species to colonize a newly disturbed or barren ecosystem.

• Plants that only grow in the desert

• Species that only live in water

• The last species to leave an ecosystem

Can you identify the pioneer species from the following options?

• Rabbits, deer, and squirrels

• Tulips, daisies, and sunflowers

• Oak trees, pine trees, and maple trees

• Mosses, lichens, and algae

What are the similarities between primary and secondary succession?

• Both involve the process of photosynthesis

• Both occur in aquatic ecosystems

• Both involve the process of ecological succession

How do primary and secondary succession differ?

• Primary succession occurs in water, while secondary succession occurs on land.

• Primary succession occurs in an area where no soil exists, while secondary succession occurs in an area where soil is already present.

• Primary succession occurs rapidly, while secondary succession takes hundreds of years to occur.

• Primary succession occurs in an area with abundant vegetation, while secondary succession occurs in a barren area.
