Energy Loss Adding trophic levels adds to energy demands 11/18/2018 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)
