Therefore, biodiversity means "different types of life." The following diagram illustrates the mangrove as nursery grounds and critical habitat in the life cycle of coral reef fish. Fringing Reefs: The fringing reefs also referred to as the shore reefs are built from the sea bottom and extend from the shore up to 1/4 miles having no navigable channel between the shore and reef. Reefs grow faster in clear water that allows sunlight to penetrate. Soft corals (Gorgonians), such as sea fans, sea whips, and sea rods, sway with the currents and lack an exoskeleton. Food webs consist of different organism groupings called trophic levels. Over many years, the accumulation of coral skeletons (mainly secretions of calcium carbonate, or limestone) creates massive reef structures, some of … Top of Page. Global Threats to Coral Reefs. Additionally, they filter the water column, prevent seabed erosion, and release oxygen essential for most marine life. Project the Coral Reef Ecosystem illustration on the board so all students can see it. Most coral reefs are built from stony corals, whose polyps cluster in groups.

Pollutants, nutrients and litter enter near shore waters through rivers, streams, underground seepage, waste water and storm water runnoff. See more ideas about Coral reef ecosystem, Coral reef, Coral reef biome. We start to see the importance of the balance set by the food webs when we see the consequences of anthropological interferences in those food webs. Have students identify and classify the coral reef organisms as vertebrates or invertebrates and discuss their characteristics in terms of structure and function. For example, overfishing of herbivorous fish often results in increased growth of algae and sea grasses. Polyps range in size from a pinhead to a foot in length. Explain that sym means "together" and bio means "life," so symbiosis means "life together," or "living together." ; They are among the most threatened ecosystems on Earth, largely due to unprecedented global warming and climate changes, combined with growing local pressures. Coral reefs harbour the highest biodiversity of any ecosystem globally and directly support over 500 million people worldwide, mostly in poor countries. When combined, all of these impacts dramatically alter ecosystem function, as well as the goods and services coral reef ecosystems provide to people around the globe. TABLE OF CONTENTS . This confines most corals to shallow waters that are clean and clear. Mangroves are salt-tolerant trees that grow along tropical and sub-tropical coasts. Marine ecosystems contain a diverse array of living organisms and abiotic processes. A food web is a system of interlocking and interdependent food chains. The total amount of fish taken from the coral reef ecosystem, is derived by multiplying the number of tourists by consumption rate. In this example of a coral reef, there are producers, consumers, and decomposers. This activity targets the following skills: The resources are also available at the top of the page.

Wrasses are a key example and provide evidence for a trophic division within crustacean-feeding taxonomy. Seagrass meadows also provide physical habitat in areas that would otherwise be bare of any vegetation. 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. If students have difficulty with the concept, give the example of students working together in a group to complete a task. There is another very important element of the reef ecosystem that is often over looked: the land. To illustrate the concept of symbiosis, show students the two images in the Symbiotic Relationships photo gallery. These wide varieties of organisms have specific roles in the ecosystem as a unit. The Great Barrier Reef is the largest coral reef in the world. Producers make up the first trophic level. The Have students play a game to match reef creatures and reef roles. For nearly all ecosystems—diverse collections of species that interact with each other and their physical environment—the major source of energy is the sun. While marine ecosystems like a coral reef are very different from terrestrial ecosystems like temperate forests, you can see how the concept of energy flow works in the exact same way. A reef ecosystem may be made up of many species of corals. Zooxanthellae take in carbon dioxide, process it through photosynthesis, and give off oxygen and other important nutrients that are then used by the host polyp. In each food web there are several trophic levels. ... are and also take a look at a couple of specific examples of coral reef food webs.
