Which consequence results when coral senses venom attack?

A)Expulsion of symbiotic zooxanthellae algae
B)Accelerated calcium carbonate skeletal deposition
C)Increased water calcification rate
D)Photosynthetic pigment concentration increases rapidly

💡 Explanation

Coral bleaching, the expulsion of symbiotic algae, occurs because chemical signals received during venom injection during predation activates the cAMP signaling pathway, halting photosynthesis, therefore it expels algae rather than reinforcing their presence. This process minimizes energy loss to predators.
