← Nature & AnimalsWhich consequence results when increased ocean acification reduces the calcification rates of corals?
A)Increased algal bloom frequency
B)Zooxanthellae expulsion and coral bleaching✓
C)Reduced fish biodiversity and abundance
D)Enhanced coral growth and resilience
💡 Explanation
Coral bleaching from decreased calcification occurs because corals rely on symbiotic zooxanthellae for nutrients established through photosynthesis; therefore, the photosynthetic output decreases leading to the expulsion of zooxanthellae, rather than enhanced coral growth under ideal conditions.
