Importance Of Coral Reefs

Coral reefs are important for many different reasons. Apart from protecting the shoreline from the damaging effects of the ocean, they provide habitats and shelter for many organisms and are the source of nitrogen and other nutrients essential for the food chain. This is why hundreds of thousands of marine species live in reefs. For example, algae called zooxanthellae live within each coral. In return for a safe sunny home, the zooxanthellae eat the nitrogen waste that the coral produces (nitrogen is very good for algal growth) and, like all plants, algae turn sunlight into sugars by the process of photosynthesis. The sugars produced by the zooxanthellae make up 98 per cent of the coral's food. So, without having to do any work at all, the coral is kept clean and well fed, and the zooxanthellae with their brilliant reds, oranges and browns give corals their colour. Many fisheries depend on the fish that spend the first part of their life in coral reefs, before making their way out to the open ocean. The Great Barrier Reef is especially important to the Australian economy and generates 1.5 billion dollars every year from fishing and tourism. In addition, the study of coral reefs can provide a history of past climates.
