Coral reefs are some of the most diverse and valuable ecosystems on Earth. They: protect coastlines from the damaging effects of wave action and tropical storms. The functions of the coral reef ecosystem include: As a Food Source. But currents also have a negative impact because currents can cause sedimentation in the waters of coral reefs and cover the surface of the reef resulting in coral death. Strive for legislation for the protection of coral reefs, so that there is no legal vacuum in the context of law enforcement for the preservation and protection of coral reefs. Coral reefs provide an important ecosystem for life underwater, protect coastal areas by reducing the power of waves hitting the coast, and provide a crucial source of income for millions of people. This flow usually comes from exhaust pipes, rainwater pipes or factory wastes which are disposed of at sea. (2 points) Ecosystem services are the benefits humans get from different aspects of ecosystem structure and function. Coral reefs actually perform a large variety of ecological functions. Coral reefs provide cultural value, with surveys finding 94% of residents agree that reefs are important to Hawaiian culture. Algae, fish, echinoderms and many other species depend on the reef for their habitat and food too. - Definition, Factors & Examples, Impact of the Industrial Revolution on Women & Children, Identifying Trends, Patterns & Relationships in Scientific Data, What Are Producers and Consumers in Biology? For example on the east coast of Africa, the south coast of India, the Red Sea, off the northeast and northwestern coast of Australia to Polynesia , the beaches of Florida, the Caribbean and Brazil. Why are coral reefs important? Biodiversity increases ecosystem functions despite multiple stressors on coral reefs. If algae are not kept in check, they can kill coral and destroy the entire reef ecosystem. In the table, give specific examples of ecosystem services coral reefs provide for other ecosystems. This coral reef ecosystem also grows in areas near the coast that have tropical ecosystems such as in Indonesia with temperatures around 210 to 300˚C. Stony corals (scleractinians) make up the largest order of anthozoans, and are the group primarily responsible for laying the foundations of, and building up, reef structures. Earn Transferable Credit & Get your Degree, Get access to this video and our entire Q&A library. An assessment of the coral reefs in U.S. waters is sounding the alarm over the role of human activity and climate change in the decline of these ecosystems. Excessive mining and extraction of coral can potentially destroy thousands of square meters of reefs and turn reefs into underwater deserts. Catching the fish using muro-ami, poisons, and explosives, can cause damage to coral reefs. Besides coral reef makes the marine world becomes aesthetic, it’s better if human could care more about marine life. In addition, coral reefs can also protect coastal benefits from abrasion and erosion due to ocean waves. So, coral reefs are lime sediments formed by calcium carbonate produced by calcium carbonate-producing marine biota which is then going through a process of sedimentation. Coral reefs are limestone sediments in the ocean zone, which are made of living corals and dead corals that attach to each other. Coral reefs supports live for a numerous amount of different species. Strive to manage the conservation of coral reef ecosystems so that they can be used optimally and efficiently for the community. Coral reefs teem with diverse life.
