question 16

Multiple Choice

  -To take advantage of ecotourism, a resort is built near a coral reef so that tourists can observe the spawning that occurs shortly after a full moon. As an added benefit, several species of colorful fishes are attracted to the area. Tour boats go out nightly and shine large spotlights to attract the fish. Tourists are enchanted by the display of fishes but have begun to question why spawning among the corals has ceased. What is the probable cause for the lack of spawning? A)  The spotlights are causing the corals to spawn during the day rather than at night. B)  The fish are eating the spawn. C)  Corals time their spawning by the phase of the moon; spotlights mimic the full moon, so spawning can't occur. D)  The tourists are too loud. E)  The fish are releasing chemical signals that interfere with spawning among the corals.
