Why are coral reefs found only in clear tropical waters?
Coral reef is independent ecosystem. Both algae and coral polyps build coral reef.
Coral reef consists of polyps and algae. Both unicellular algae and filamentous algae are present in polyps. In dead skeleton of coral there is filamentous algae. While unicellular algae is in the body of polyps. The polyp releases carbon dioxide . The carbon dioxide is used by algae . The complete recycling of matter takes place in corals. For photosynthesis of algae it needs light and clear water. This is the reason why in turbid water corals are unable to survive.

Coral reefs are found only in clear tropical waters because coral polyps, which build the reefs, require sunlight for photosynthesis. Clear water allows sunlight to penetrate deep into the ocean, providing the necessary energy for coral growth. Additionally, coral reefs thrive in warm water with temperatures typically between 20-32°C (68-90°F), which is characteristic of tropical regions. The clarity of the water also aids in nutrient availability and planktonic food sources for the coral organisms.
