← Nature & AnimalsWhich consequence results when a dinoflagellate bloom depletes nutrients?
A)Decreased bioluminescent flash intensity✓
B)Elevated toxin production rate
C)Increased cell division synchronicity
D)Greater vertical migration distances
💡 Explanation
Reduced nutrient availability inhibits luciferase enzyme production, which decreases bioluminescent flash intensity because the cells lack sufficient resources; therefore, dim flashes occur rather than sustained bright glows, influencing predator avoidance effectiveness.
