Ecological Succession Quiz

What is ecological succession?

• The process of one species evolving into another

• The process of ecological change in an ecosystem where one community is replaced by another over time

• The study of how ecological communities form and develop

• The migration of species from one ecosystem to another

Which of the following is an example of primary succession?

• A forest regrowing after a wildfire

• Mosses and lichens growing on exposed rock

• A garden being planted in a backyard

• Animals repopulating an abandoned city

What role do pioneer species play in primary succession?

• They decompose organic material to release nutrients

• They are the final species to appear in a succession sequence

• They prevent other species from growing

• They create a more habitable environment for subsequent species

What is a climax community?

• The initial stage of an ecological succession

• A temporary community that changes frequently

• A mature and stable community of plants and animals

• A community that exists only for a short period

What is secondary succession in an ecosystem?

Which of the following is a typical pioneer species in secondary succession?

• Tall trees and shrubs

• Weeds and grasses

• Aquatic plants

• Mosses and lichens

Why does secondary succession typically occur more quickly than primary succession?

• Because the soil is completely removed and needs to be formed anew.

• Because it occurs in areas without any previous biological activity.

• Because the soil remains intact and contains some seeds and microorganisms.

• Because it involves the introduction of entirely new species.

What defines a stable ecosystem?

• An ecosystem that changes frequently with unpredictable patterns.

• An ecosystem that has no living organisms.

• An ecosystem that remains relatively constant, with predictable changes.

• An ecosystem that is newly formed and rapidly changing.
