How Does the Suns Energy Flow Through an Ecosystem?
Students play “The Photosynthesis Game” to identify the components in the environment that are necessary for plants to produce their own food. Cooperative groups make blocks from small milk cartons and together, as a class, they design a food pyramid. They participate in both a demonstration and a relay to show that energy is lost when it is transferred from producers to consumers. Lesson 6. What Interrelationships and Niches Can Be Identified in an Ecosystem? Students list different ways that living things can depend on one another. Students go outside and identify an organism’s relationships to other living things. The class adds organisms to the ecosystem tube designed in Lesson 3 and describes how energy in the tube is passed from organism to organism. Groups draw a food chain, which includes organisms from their habitat bottles. Students design a bulletin board to show the interactions of a grassland ecosystem. They draw and construct several food chains and diagram ways organisms
