Which 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.
