Energy flow in Ecosystems 11/16/2018 Energy flow in Ecosystems Producers Photosynthesis Consumers All others Trophic levels Assigning organisms levels Fig. 6 p.345

From: http://www.kesgrave.suffolk.sch.uk/ 11/16/2018 Trophic levels 1st Producers 2nd herbivores 3rd Omnivores, carnivores Rarely there are 4 trophic levels (carnivores that eat other carnivores) Detrivores (decomposers) From: http://www.kesgrave.suffolk.sch.uk/ learningzone/subjects/geography/trophic.html

Energy Loss Adding trophic levels adds to energy demands 11/16/2018 Energy Loss Adding trophic levels adds to energy demands Decrease of factor of 10 with additional trophic level Each trophic level has 90% less energy than the one below it Three hundred trout are needed to support one man for a year. The trout, in turn, must consume 90,000 frogs, that must consume 27 million grasshoppers that live off of 1,000 tons of grass.  -- G. Tyler Miller, Jr., American Chemist (1971)
