Question

Quizplus · Accepted Answer

Algal ingestion from ocean waters is not a negative influence on coral symbiosis. In fact, many coral species have a mutualistic relationship with certain types of algae, called zooxanthellae, which live inside their tissues and provide them with nutrients through photosynthesis. The other options listed (increasing temperatures, freshwater runoff, alterations in UV light intensity, and changing pH) can all have negative impacts on coral symbiosis by stressing the corals or disrupting the balance of their relationships with their zooxanthellae.
