I. Not all energy is transferred from one trophic level to another. The third type of coral reef is the platform reef which generally grows either on the continental shelf or in the open ocean with some being found close to 124 miles from the shoreline. The average slope is about 45° but some barrier reefs are character­ized by 15°-25° slope. LeSSON 3 Human impact on Coral Reefs Lesson at a Glance In this lesson students will have a class discussion on the ecological importance of coral reefs and their value to humans. Type # 2. Place students in an area where they have room to mingle amongst each other. Barrier reefs are the largest, most extensive, highest and widest reefs of all types of coral reefs. The teacher will be able to assess what students already know about corals, algae, and the organisms that live on reefs and how the students relate to the reef. Coral reefs provide about 10% of the fish caught worldwide. While they wait, have them look at the Coral Reef Ecosystem illustration and its key, identify their reef creature, and practice describing the role the organism plays in the reef ecosystem. Barrier Reef: The largest coral reefs off the coastal platforms but parallel to them are called barrier reefs (fig. Oceans, estuaries, coral reefs and coastal ecosystems … Each type of survey is used to identify the species, diversity, and number of corals. “Well-managed” reefs can yield between 5 and 15 tons of fish, crustaceans, molluscs and other invertebrates per square kilometer. A food web consists of all the food chains in a single ecosystem.Each living thing in an ecosystem is part of multiple food chains. 1. There was once a hard coral colony growing on a coral reef. 30.2). An ecosystem comprises both the biotic and abiotic factors in a specific area. Aquatic ecosystems are generally divided into two types --the marine ecosystem and the freshwater ecosystem. Identify basic needs for organisms to survive. Draw a large (two ring) Venn Diagram on the board. The largest water ecosystem is the marine ecosystem, covering over 70 percent of the earth's surface. Each food chain is one possible path that energy and nutrients may take as they move through the ecosystem. (Photo: Jim Larson) ... Students will distinguish the different types of coral reefs (fringing, barrier, atoll) and identify the ... For each problem, draw a picture to help you find the answer. Coral Reef Teacher’s Guide E - 1 The coral polyp at night with ex tended tentacles. goatfi sh, Survival in the Coral Reef Habitat A. Students make transect and quadrat surveys using a provided worksheet in order to understand the techniques used to study coral reefs. Coral Reef Basics. Give each student a picture of a coral reef organism (i.e. Branching corals: this type is most commonly associated with the most colorful small corals, and are made up of a tree-like structure with multiple branches and secondary branches. Platform reefs do not have a single consistent size with several of the larger ones extending a couple of miles across while the smaller ones are some feet across. These features include the physical, biological and chemical aspects of a specific habitat. 1. Coral Reef Introduction: Draw a Coral Reef - Students draw a picture of a coral reef based on prior knowledge. That discussion will lead the class to examine the threats to reefs both by humans and by nature. But this figure rises to 20-25% in developing countries, and 70-90% in Southeast Asian countries.
