Question

Quizplus · Accepted Answer

Coral reefs rely heavily on sunlight for photosynthesis, which is necessary for their survival. The euphotic zone is the area of the ocean where enough sunlight can penetrate for photosynthesis to occur, and coral reefs can only survive within this zone. Therefore, inadequate sunlight is the main factor that prevents coral reefs from surviving below the euphotic zone.
