Question Detail
Question
Which of the following serves as a functional barrier even if two habitats are physically connected?
Correct Answer
Option C is the correct answer.
Detailed Explanation
Unsuitable terrain (e.g., a desert between two forests) acts as a barrier because species cannot survive long enough to cross it. Corridors and riparian zones actually aid movement.
Hint
Consider 'gaps' in the landscape that a species cannot utilize.
