Measuring the rugosity of a coral reef : A: Is usually done in a lab setting B: Can give us valuable information about the structural complexity of a reef habitat C: Is not a useful measurement because it does not give information about how the benthos functions. D: Gives us the same type of information as a line-intercept survey
