Corals are composed of thin plates, or layers, of calcium carbonate secreted over time by hundreds of soft bodied animals called coral polyps. Students learn about reef ecology with a focus on biodiversity and symbiotic relationships in the coral reef ecosystem. A reef is a ridge of material at or near the surface of the ocean. Coral reefs are some of the most diverse ecosystems in the world. Code of Ethics. Each time two students think they have matched their cards correctly, confirm their match. It is estimated that 17 species of coral reef fish spend their entire juvenile life stage solely on seagrass flats. In addition to forming energy, the interaction between these components also … Help students group themselves so that each location has a variety of creatures, not fish or invertebrates only. Have students identify and classify the coral reef organisms as vertebrates or invertebrates and discuss their characteristics in terms of structure and function. These reefs provide food and habitat for about 25 percent of the world’s fishes. In this worksheet students will be challenged to use information from multiple sources about coral reefs. Fringing reefs grow near the coastline around islands and continents. Coral reefs harbour the highest biodiversity of any ecosystem globally and directly support over 500 million people worldwide, mostly in poor countries. Reef Fish Behavior: Florida, Caribbean, Bahamas. the coral reef and mangrove ecosystems form a barrier that protects shorelines from the destructive forces of wind, waves and driven debris. 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. Types of Coral Reefs: The various types of coral reefs are grouped into three major types: 1. 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. Over many years, the accumulation of coral skeletons (mainly secretions of calcium carbonate, or limestone) creates massive reef structures, some of … Each polyp lives in a symbiotic relationship with a host zooxanthellae that gives the coral its color. 6001 Highway A1A Indian River Shores, FL 32963 Tel: 321-431-6595 all the different kinds of living organisms within a given area. community and interactions of living and nonliving things in an area.

The production of limestone-like calcium carbonate is high enough in many warm-water coral reefs to establish carbonate structures. A food web is a system of interlocking and interdependent food chains. Terms of Service |  Seagrass meadows also provide physical habitat in areas that would otherwise be bare of any vegetation. There is another very important element of the reef ecosystem that is often over looked: the land. Coral Reef Types. Seagrass also provides protection and shelter for commercially valuable species such as stone crabs, snappers and lobsters. Tell students that ecosystems with high biodiversity also show a high number of symbiotic relationships between the organisms that live there. Angela M. Cowan, Education Specialist and Curriculum Designer. The total amount of fish taken from the coral reef ecosystem, is derived by multiplying the number of tourists by consumption rate. For example, overfishing of herbivorous fish often results in increased growth of algae and sea grasses. Many of the animals raised in mangroves migrate to coral reefs for food, spawning and habitat. Food webs consist of different organism groupings called trophic levels. Global Threats to Coral Reefs. Reefs are formed of colonies of coral polyps held together by calcium carbonate. 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. Fringing reefs are the most common type of reef that we see. 2. The number of fish caught in coral reef fishing is already 64 percent higher than what can be sustained.

The trophic level of an organism is the position it occupies in the food chain. Coral reefs also offer many ecosystem services to communities, such as protecting coastlines and houses from storm waves. Its 2,500 individual reefs and 900 islands extend from the northern tip of Queensland down to south of Gladstone, and its ecosystems range from shallow near shore environments to deep waters 250 kilometres offshore. Coral reefs harbour the highest biodiversity of any ecosystem globally and directly support over 500 million people worldwide, mostly in poor countries. Ask students to carefully read the information provided on their cards. Hard corals (Scleractinia), such as brain, star, staghorn, elkhorn and pillar corals have rigid exoskeletons, or corallites, that protect their soft delicate bodies. There are natural and artificial reefs. Coral reefs are one of the most biologically diverse ecosystems on earth, rivaled only by tropical rain forests. Wrasses are a key example and provide evidence for a trophic division within crustacean-feeding taxonomy. Both warm- and cold-water corals secrete calcium carbonate skeletons that build up over time to create a three-dimensional reef matrix that provides habitat for thousands of fish and other species. 1. Mangroves are salt-tolerant trees that grow along tropical and sub-tropical coasts. 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.

Coastal ecosystem is defined as an ecosystem which is a unit of both biotic and abiotic components that are around the coast, interact with each other, and influence yet form an energy flow. Where there is a coral reef, there must be the crustaceans. If there is an odd number of students, you will need to participate or have two students work as a buddy pair that counts as one student. Primary producers in a coral reef environment are mostly microscopic plankton, microscopic plant-like organisms found in the coral and free-floating in the water around the coral reef. Coral reef ecosystems are amongst the most diverse and complex ecosystems on Earth. You cannot download interactives. }. Healthy reefs are typically colorful, highly biodiverse areas made up of a mishmash of corals and the species that inhabit them, such as fish, sea turtles , and invertebrates such as sponges , shrimp, lobsters, crabs, and seahorses . Coral reefs provide critical ecosystem services including shoreline protection and food security to coastal communities worldwide [].The maintenance of these services depends on a balance between coral reef growth (accretion) and reef breakdown (bioerosion and dissolution), where accretion must be greater than erosion for reef persistence. Invasive species can create an imbalance in the biological checks and balances of a reef ecosystem. While natural causes such as hurricanes and other large storm events can be the stimulus for such alterations, it is more commonly anthropological forces that effect these types of shifts in the ecosystem. Whether it’s the Great Barrier Reef off the coast of Australia, or a miniature coral reef ecosystem in your tank, it doesn’t matter. All rights reserved. Coral reef fish consumption by tourists, set to 0.158 originally, positively relates to local fish catch, thus negatively relating to the algae extinction rate.
