검증된 단계별 안내1
Understand the concept of secondary succession: Secondary succession refers to the ecological process where an ecosystem recovers after a disturbance, such as a fire, flood, or human activity, in areas where soil is already present.
Compare secondary succession to primary succession: Primary succession occurs in areas where no soil or organic matter exists, such as bare rock after a volcanic eruption. Secondary succession, on the other hand, starts in areas where soil and organic matter are already present.
Analyze the given statements: Evaluate each statement based on the definition of secondary succession. For example, the statement 'Secondary succession only occurs in aquatic environments' is incorrect because secondary succession can occur in terrestrial environments as well.
Focus on the correct statement: The statement 'Secondary succession occurs in ecosystems where soil is already present' aligns with the definition of secondary succession, making it the correct answer.
Conclude by eliminating incorrect options: Discard statements that contradict the definition of secondary succession, such as 'Secondary succession results in the formation of soil from bare rock' and 'Secondary succession occurs in areas completely devoid of soil and organic matter.'
