← Nature & AnimalsWhich phenomenon inhibits rapid coral growth when sedimentation increases?
A)Reduced zooxanthellae photosynthetic output✓
B)Enhanced nutrient uptake via phagocytosis
C)Increased coral polyp respiration rate
D)Accelerated deposition of calcium carbonate
💡 Explanation
Increased sedimentation reduces light penetration, inhibiting photosynthesis by zooxanthellae. This diminished Carbon fixation then limits energy available for coral growth. This reduction rather than increase accelerates growth or switches energy usage.
