Question

Quizplus · Accepted Answer

The question is asking about the algae that live in symbiotic relationship with coral. These algae are called zooxanthellae and they perform photosynthesis. Therefore, choice C is the correct answer because it states that photosynthesis (which is what zooxanthellae do) must live in water that is penetrated by light. Choices A, B, D, and E are not correct because they mention chemosynthesis, which is not what the algae in this particular symbiotic relationship do.
