Presentation on theme: "ECOSYSTEMS FOOD CHAINS AND WEBS. ENERGY FLOW IN ECOSYSTEMS The greatest amount of energy is in the bottom level- or the producers Producers are photosynthetic."— Presentation transcript:
Teacher Notes Begin with BrainPop- category: “Ecology and Behavior”, videos: “Ecosystems”, “Food Chains”, “Symbiosis” This vocabulary is heavily TAKS tested, so the students need lots of practice making connections between the terms. Have the students take notes on the power point, then have them define the vocabulary at the end. Have the students create a food chain and food web based on organisms from either a desert environment, a forest environment, or a marine environment. They must have a producer, primary consumer, secondary consumer, tertiary consumer.
Continued….. Have students group organisms in categories of: autotrophs, heterotrophs, consumers, producers, omnivores, herbivores, carnivores. Example: Carnivores are also: predators, consumers, heterotrophs. Autotrophs are also: producers, photosynthetic, bottom of the food chain. Have students turn in webs and classifications to their science teacher for extra credit!
