What is ecological succession?

• A rapid change in non-living environments

• A gradual change in living communities following a disturbance

• The process by which new species evolve from old species

• A method of conserving endangered species

What occurs during primary succession?

• It happens in areas where soil is already present

• It occurs only in aquatic environments

• It happens when a new patch of land is created or exposed for the first time

• It involves the immediate return of species that previously inhabited an area

What is secondary succession?

• Succession that starts on bare rock

• Succession that occurs where soil exists but has been disturbed

• Succession that happens after a volcanic eruption

• The final stage of succession where no further changes occur

Which of the following best describes the significance of ecological succession and human impact on the environment?

• It highlights the role of humans in preventing natural disasters

• It shows how human activities can accelerate or hinder ecological succession

• It indicates that humans have no significant impact on ecological processes
