A food web model is a network of food chains. Each food chain starts with a primary producer or autotroph, an organism, such as an alga or a plant, which is able to manufacture its own food. Next in the chain is an organism that feeds on the primary producer, and the chain continues in this way as a string of successive predators.
Coral reefs also support a huge community of life, including the corals themselves, their symbiotic zooxanthellae, tropical fish and many other organisms. Much attention in marine biology is focused on coral reefs and the El Niño weather phenomenon. In 1998, coral reefs experienced the most severe mass bleaching events on record, when vast ...
Due to Hawaii's isolation 30% of the fish are endemic (unique to the island chain). [1] The Hawaiian Islands comprise 137 islands and atolls, with a land area of 6,423.4 square miles (16,636.5 km 2). [2] This archipelago and its oceans are physiographically and ethnologically part of the Polynesian subregion of Oceania.

These include the rich habitat complexity and diversity inherent in coral reef ecosystems, [4] [5] the wide variety and temporal availability of food resources available to coral reef fishes, [6] a host of pre and post-larval settlement processes, [7] and as yet unresolved interactions between all these factors. The wealth of fishes on reefs is ...
A 2015 bleaching event wiped out half of Hawaii's coral reefs, and most were off of Hawaii Island and Maui's shores. In the worst-case scenario, scientists say coral reefs could be extinct in 30 ...
Coastal fish are found in the waters above the continental shelves that extend from the continental shorelines, and around the coral reefs that surround volcanic islands. . The total world shoreline extends for 356,000 km (221,000 mi) [3] and the continental shelves occupy a total area of 24.3 million km 2 (9 376 million sq mi)
