Ecology Unit 2 Th 9/22, Fri 9/23 block Lesson 3.2B Lesson objective: students learn about feeding relationships in ecosystems and energy pyramids State standard: 6e, 6f Vocabulary Producer- autotroph (self-feeder) organism that can make its own food Consumer- heterotrophy (other feeder) organism that needs food to survive Herbivore- animals that eat only plants Carnivore- animals that eat only other animals Omnivore- animals that eat both plants and animals Decomposers- (bacteria, fungi) break down dead organisms, recycling their nutrients Food web- the network of feeding relationships in an ecosystem Trophic level- a step in a food chain or web. Producers are always at the lowest level Ecological pyramid- a diagram that show how energy, biomass, and numbers of individuals decreases from the bottom to the top (10% per level) CFU: examples and non-examples of vocabulary terms, activating prior knowledge Lesson: lecture 3.2 Energy Flow in ecosystems Pair/share: what would happen if………………carnivores die, producers die, decomposers die? White board: How are the trophic levels interdependent? Guided practice: chart a typical food web found in a Sonoma back yard Lab : Backyard food web (Glencoe) Unit Project introduction: Biomes art collage
