what two important functions do coral reefs provide an ecosystem?

Coral reefs are considered as one of the most spectacular marine ecosystems on Earth. Coral reefs posses an … Coral reefs, thanks to their diversity, provide millions of people with food, medicine, protection from storms, and revenue from fishing and tourism. Coral reefs are one of the most biological diverse ecosystems on Earth. Coral reef ecosystems also have an important function as nursery habitats for reef-associated sharks. Coral reefs rely on mutualisms between corals and unicellular algae living in the corals tissues to enhance coral growth and produce the physical structure that provides a living space for thousands of other reef organisms. But this figure rises to 20-25% in developing countries, and 70-90% in Southeast Asian countries. Coral reefs provide the spawning and nursery grounds that economically important fish populations need to thrive. Climate change will affect coral reef ecosystems, through sea level rise, changes to the frequency and intensity of tropical storms, and altered ocean circulation patterns. But conservation innovation and technology can help. They provide food for many organisms within the ecosystem. An estimated 4,000 fish species, and some 25 percent of marine life, depend on coral reefs at some point in their existence. 2005). Visualizing changes in the capacity of coral reefs to underpin three ecosystem services: (a) to (f) are multidimensional spaces with axes representative of biomass and species richness (traits) of the reef fish community (service provider) that are significant in the provisioning of three ecosystem services from coral reefs: underwater tourism, an aquarium fishery and a multispecies food fishery. They do, however, play an important role in driving consensus around how to measure and monitor ecosystems like coral reefs and the benefits they provide to people. Coral reefs are in a perilous state. Occupying less than one percent of the ocean floor, coral reefs are home to more than twenty-five percent of marine life. They play a matching game to identify reef organisms and roles and they discuss human threats to coral reef health. Some of these services, or functions, include protecting and improving water quality, providing fish and wildlife habitats, storing floodwaters and maintaining surface water flow during dry periods. What Do Coral Reefs Need to Survive? This is a remarkable statistic when you consider that reefs cover just a tiny fraction (less than one percent) of the earth’s surface and less than two percent of the ocean bottom. (c) and (d) display how, in maintaining the status quo, different functions would be considered critical through time. Protection from storms: Coral reefs are also our first line of defense against tropical storms, helping to protect all of our coastal communities. Our review sug-gests that most ‘functional’ studies do not study function as it relates to ecological processes. This provides many benefits to the islands themselves, including protection from high seas as well as being part of a large ecosystem that benefits the entirety of the ocean. Marine species rey on the reef ecosystem for survival and many other animals and plants inhabiting the coral reef ecosystem have developed symbiotic relationships in order to survive. • Coral reefs house between 600,000 and 9 million species • 25% of marine species rely on coral reefs at some point in their life cycle • 32 of the 34 phyla of metazoans live on reefs • 65% of marine fishes live in reefs Mangroves and seagrass beds are two of the most important associated habitats of the greater coral reef ecosystem. Not only as a shelter and food resources for many living beings but the importance of coral reefs … Habitat: They support 25% of all marine animals, from thousands of fish species to sponges to marine mammals. Coral reefs provide about 10% of the fish caught worldwide. Because coral colonies serve as the foundations of coral reef ecosystems, their decline may translate into a loss of habitat for numerous plant and animal species that depend on them. They teem with life, with perhaps one-quarter of all ocean species depending on reefs for food and shelter. We examined data from over 300 sites throughout the Caribbean, where many coral reefs have low coral cover, and thus may provide a window into the future for reef ecosystems as coral declines globally. Coral Reefs: Ecosystems Full of Life Coral Reefs: Ecosystems Full of Life Students learn about reef ecology with a focus on biodiversity and symbiotic relationships in the coral reef ecosystem. Coral reefs support more species per unit area than any other marine environment, including about 4,000 species of fish, 800 species of hard corals and hundreds of other species. Although deep water corals do exist, the majority of reef builders like to be in shallow waters, where sufficient sunlight can penetrate to fuel the photosynthesis of the algae that lives alongside the coral animals and provides them with essential food. Introduction. Habitats such as shallow sand flats [79] , mangrove habitats [80] , lagoons [80] , and tidal pools [81] function to reduce predation risk and provide resources for juveniles before they undertake ontogenetic shifts towards deeper reef slope environments [56] . “Well-managed” reefs can yield between 5 and 15 tons of fish, crustaceans, molluscs and other invertebrates per square kilometer. Coral reefs help to protect coastal communities from storm surges and erosion from waves, both of which are likely to increase in the face of sea-level rise. Coral reefs provide important protection for coasts and coastal populations against the destructive forces of the sea under storm conditions. There are 14 coastal ecosystems that are important to the function of the Reef: coral reefs, lagoon floors, islands, open water, seagrass, coastline, estuaries, freshwater wetlands, forested floodplains, health and shrublands, grass and sedgelands, woodlands, forests, and rainforests. Coral reefs are vital for a healthy ecosystem. Thousands of species can be found living on one reef. They provide protection by stabilizing the coastline with their complex root system. Reef animals are an important source of protein. Caribbean coral reefs extend from the Greater and Lesser Antilles through the islands of The Bahamas. Plants Besides fish, several types of plants are found within coral reefs. Coral reef is one from many ocean ecosystem that we see frequently. Coral reefs are some of the most diverse and valuable ecosystems on Earth. Coral Reefs overall biodiversity • Coral reefs are believed by many to have the highest biodiversity of any ecosystem on the planet—even more than a tropical rainforest. After thousands of years of active coral growth, Caribbean reefs have lost 80% of their coral cover over only the last two decades – other reefs seem similarly threatened. The majority of tourists that visit Hawai‘i engage in marine-based activities, including diving and snorkeling (Beukering & Cesar 2004), and fish diversity is one amongst a variety of factors that drives visitor destination choice (Uyarra et al. On tropical coral reefs, the ocean’s most diverse ecosystems, remarkably few studies directly quantify ecosystem functions and the term ‘function’ is widely used but rarely defined, especially when applied to reef fishes. Coral reefs have existed on Earth for 500 million years, providing shelter and food to many generations of ocean life. Sunlight: Corals need to grow in shallow water where sunlight can reach them.
