Which bleaching consequence results when thermal stress impairs zooxanthellae?

💡 Explanation

Coral bleaching happens because high temperatures cause zooxanthellae to be expelled; therefore, the coral suffers starvation due to impaired photosynthesis decreasing nutrient availability, rather than increased calcification as zooxanthellae support that process.
