Question
What biological mechanism can restrict a species' range because it depends on another specific organism?
Correct Answer
Option D is the correct answer.
Detailed Explanation
Mutualism, such as the relationship between a specialist pollinator and a plant, limits the range of both organisms to where the partner exists. Endemism describes the range, but mutualism is the mechanism causing the restriction.
Hint
Think of relationships where two species need each other to survive.
