Matching Pairs Energy Flows Food Chains & Food Webs FlashcardsOnline version Energy Flows (Food Chains & Food Webs) Flashcards by Benjamin D Morgan 1 Thermal Energy 2 Why only 10% of energy is transferred to the next trophic level 3 Primary Consumer 4 Solar Energy 5 90% 6 10% 7 Dependent Variable 8 Food Web 9 Tertiary Consumer 10 Independent Variable 11 Producers/Autotrophs 12 Food Chain 13 Secondary Consumer 14 Trophic Levels 15 Energy Pyramid 16 Chemical Energy 17 Controlled Variable 18 Energy Eats producers to get energy and is in the second trophic level of the energy pyramid. Different feeding positions in a food chain or web. The amount of energy passed when one organism eats another in the next trophic level. The variable that is kept the same in an experiment so that the results are not thrown off. We need as many as possible of these The variable that is measured in an experiment. The effect in an experiment. We can have only one of these in an experiment Type/form of energy each organism in a food chain is AND the form of energy passes along from one organism to another. The variable that is changed in an experiment. The cause. We can have only one of these in each experiment Energy is lost due to unusable heat and waste series of steps in an ecosystem in which organisms transfer energy AND transfer matter by eating and being eaten Food chains show a flow of ________ from the organism that is eaten to the organism that is eating it. A group of overlapping food chains connected together in an ecosystem (complex). Type of energy lost to the environment in a food chain Amount of energy lost to the environment as heat OR used by the organism to stay alive Eats herbivores to get energy and is in the third trophic level of the energy pyramid. A possible start to the food chain and are in the first trophic level of an energy pyramid A good way to show how energy moves from one feeding level to another in a food chain. Eats other carnivores to get energy and is in the fourth energy level of the trophic level. Original source of energy for a food chain
