Republic of the Philippines SOUTHERN LUZON STATE UNIVERSITY Lucban, Quezon Laboratory Exercise No.1 aquatic Ecosystem I. Introduction Often called rainforests of the sea, chromatic reefs variate close to of the some diverse ecosystems on earth. They occupy less than hotshot one-tenth of one percent of the world oceanic surface, to the highest degree fractional the bea of France, yet they provide a home for xxv percent of all marine species, including fish, molluscs, worms, crustaceans, echinoderms, sponges, tunicates and other cnidarians. Paradoxically, chromatic reefs swank even though they atomic number 18 butted by ocean waters that provide few nutrients. They are nigh commonly found at shallow depths in tropic waters, simply deep water and cold water corals too constitute on smaller scales in other areas. in that respect are three types of coral reefs: fringing, barrier and atoll. Fringing reefs border shorelines of continents and islands in tropical seas. The next type is the barrier reef, which occurs farther offshore. bar reefs form when land masses sink, and fringing reefs become separated from shorelines by colossal channels. If the land mass is a small island, it may at last disappear below the ocean surface, and the reef becomes an atoll. Atolls are reefs that surround a central lagoon. The result is several(prenominal) low coral islands around a lagoon.
II. Components of Coral take down Ecosystem A. Abiotic Components The major fraction is water which provides the habitat and the environment. Dissolved compounds such(prenominal) as atomic number 11 chloride directly min! t salinity of the water. Sunlight regulates water temperature. The nominal head of divergent nutrients is similarly another abiotic component. Bottom substrate and rocks are also important components. B. Biotic Components 1. Producers Photosynthetic organisms are the primary(prenominal) producers in a coral reef ecosystem. These include phytoplankton, seaweeds, as well as the microscopic zooxanthellae that have a dependent relationship with the coral polyps.
