Matching Pairs Energy Flows Food Chains & Food Webs FlashcardsOnline version Energy Flows (Food Chains & Food Webs) Flashcards by Benjamin D Morgan 1 Controlled Variable 2 Food Web 3 10% 4 Energy Pyramid 5 Solar Energy 6 Primary Consumer 7 Thermal Energy 8 Tertiary Consumer 9 Producers/Autotrophs 10 Why only 10% of energy is transferred to the next trophic level 11 Dependent Variable 12 Independent Variable 13 Energy 14 Secondary Consumer 15 90% 16 Food Chain 17 Chemical Energy 18 Trophic Levels Type/form of energy each organism in a food chain is AND the form of energy passes along from one organism to another. Amount of energy lost to the environment as heat OR used by the organism to stay alive Different feeding positions in a food chain or web. 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 A group of overlapping food chains connected together in an ecosystem (complex). Eats herbivores to get energy and is in the third trophic level of the energy pyramid. series of steps in an ecosystem in which organisms transfer energy AND transfer matter by eating and being eaten The variable that is changed in an experiment. The cause. We can have only one of these in each experiment The amount of energy passed when one organism eats another in the next trophic level. Type of energy lost to the environment 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 Food chains show a flow of ________ from the organism that is eaten to the organism that is eating it. A good way to show how energy moves from one feeding level to another in a food chain. A possible start to the food chain and are in the first trophic level of an energy pyramid The variable that is measured in an experiment. The effect in an experiment. We can have only one of these in an experiment Eats producers to get energy and is in the second trophic level of the energy pyramid. Energy is lost due to unusable heat and waste
