Nesting Sites Division of Academics – Department of Science Third Nine Weeks OBJECTIVES Analyze food webs to determine the roles, relationships, and transfer of energy among organisms Compare and contrast the relationships among organisms, including predation, parasitism, competition, commensalism, and mutualism Explain and illustrate the relationships among decomposers, producers and consumers, in the process of energy transfer in an ecosystem including food webs Explain the pathway of energy transfer through producers, and primary, secondary and tertiary level consumers Analyze various limiting factors in an ecosystem and their impact on native populations Investigate and write to explain the factors that affect population changes in an ecosystem (e.g., food, shelter, water, space, disease, parasitism, predation, and nesting sites) 10 Days 5 Days Date(s) 02-24-17 to 03-09-17 02-24-17 to 03-09-17 INSTRUCTIONAL TOOLS Core Text Book: Pearson Interactive Science Florida Ch. 14 Vocabulary: decomposer, consumer, producer, symbiosis, herbivore, carnivore, omnivore, food web, food chain, food pyramid, mutualism, commensalism, parasitism, predation, ecosystem, primary consumer, secondary consumer, tertiary consumer, energy pyramid, competition, limiting factors, population, autotroph, heterotroph, niche Technology: 1.
