Which outcome results on coral reefs when El Niño events induce thermal stress?

💡 Explanation

Coral bleaching happens because thermal stress during El Niño inhibits zooxanthellae photosynthesis via photoinhibition, therefore expulsion occurs, rather than enhanced deposition because that relies on stable temperatures.
