explain how mangrove ecosystems and coral reef ecosystems are similar

Global Threats to Coral Reefs. The coral provides a protected environment and the compounds zooxanthellae need for photosynthesis. Invasive species can create an imbalance in the biological checks and balances of a reef ecosystem. Other threats are caused by people, including pollution, sedimentation, unsustainable fishing practices, and climate change, which is raising ocean temperatures and causing ocean acidification. Saltmarshes tend to grow on the landward side of mangroves where saltwater inundation occurs less frequently (usually only during high spring tides). Identify common and endangered plant and animal species found in coastal ecosystems. 1). This confines most corals to shallow waters that are clean and clear. What Is This Game? GLOBAL STATUS OF CORAL REEFS AND MANGROVES Coral reefs and mangroves are two of the world’s rarest ecosystems, covering an area that is an order of magnitude less than that of tropical and subtropical forests. Competition for resources such as food, space and sunlight are some of the primary factors in determining the abundances and diversity of organisms on a reef. They are made up not only of hard and soft corals, but also sponges, crustaceans, mollusks, fish, sea turtles, sharks, dolphins and much more. The ocean supports a great diversity of marine ecosystems, including abyssal plain (deep sea coral, whale fall, brine pool), Antarctic, Arctic, coral reef, deep sea (abyssal water column), hydrothermal vent, kelp forest, mangrove, open ocean, rocky shore, salt marsh, mudflat, and sandy shore. They are represented on all continents with tropical and subtropical coasts, i.e. Even areas hundreds of miles from the coast can effect the clarity and quality of water flowing to the reef. Figure 3.1 provides a general distribution of mangrove ecosystems in the NGoM. Mangroves are salt-tolerant trees that grow along tropical and sub-tropical coasts. Numerous independent or interacting factors control the condition, sustainability, and distribution of mangrove ecosystems. Coral reefs are some of the most diverse ecosystems in the world. Some 30 per cent of reefs are already seriously damaged and 60 per cent could be lost by 2030. Both ecosystems are under serious threat. Fewer still realize that corals are dying off at alarming rates. Coral Reef Biodiversity Biodiversity is the variety of living species that can be found in a particular place—region, ecosystem, planet, etc. Explain the ways in which humans value and use coastal ecosystems. Describe examples of food webs and energy flow in coastal ecosystems. Increased ocean temperatures and changing ocean chemistry are the greatest global threats to coral reef ecosystems. Marine ecosystems cover more than 70% of the Earth’s surface and have a high salt content. Mangrove forests or mangals are a type of intertidal wetland ecosystems. There is another very important element of the reef ecosystem that is often over looked: the land. They also extend outwards from the coast to include offshore systems, such as the surface ocean , pelagic ocean waters, the deep sea , oceanic hydrothermal vents , and the sea floor . Kelp forest, coral reefs and open ocean ecosystems. Scientists are also testing new ways to help coral reef ecosystems, such as growing coral in a nursery and then transplanting it to damaged areas. Mangroves are the only trees that are capable of thriving in salt water. Because of the diversity of life found in the habitats created by corals, reefs are often called the "rainforests of the sea." Since both partners benefit from association, this type of symbiosis is called mutualism. Their roots are submerged by seawater during the daily tidal cycle. The word mangrove is derived from the Portugese word mangue which means “tree” and the English word grove which is us… Coral reefs are some of the most diverse and valuable ecosystems on Earth. It is a large brown algae. Have a whole-class discussion about the food web display. The net economic value of the world’s coral reefs is estimated to be nearly tens of billionsoffsite link of U.S. dollars per year. This area supports more than 7,000 species of fishes, invertebrates, plants, sea turtles, birds, and marine mammals. Mangrove forests play an important role in a coastal ecosystem. Their global distribution is shown below: Using the map above describe… ... NO different species can have very similar niches, but there must be distinct differences between any two niches. Soft corals (Gorgonians), such as sea fans, sea whips, and sea rods, sway with the currents and lack an exoskeleton. Picture climate: How can we learn from corals. Additionally, they filter the water column, prevent seabed erosion, and release oxygen essential for most marine life. ecosystems function. Provide shelters and food to fish Fishing, diving, and snorkeling on and near reefs add hundreds of millions of dollars to local businesses. Barrier reefs are coral reefs extending roughly parallel and in close proximity to the shoreline. For example, overfishing of herbivorous fish often results in increased growth of algae and sea grasses. If you examine closely the different habitats on land and in water, you will … Even if you don't live near a reef, students can learn that they can help protect coral reefs in the United States and around the world. Special Microecosystem. Reefs are huge deposits of calcium carbonate made up mainly of corals. List the two characteristics that make mangroves the basis for mangrove ecosystems.
