The terms energy extraction efficiency and absorption/assimilation efficiency are defined. The grasshopper Poecilocerus pictus extracts 15 or 27% energy contained in the food plant Calotropis gigantea, when the test animals were fed from hatching to death at 26 or 36°C. The energy extraction efficiency of some insects (Bombyx and Hyalophora: terrestrial herbovores; Pyrrhosoma: aquatic carnivore) is about 7%, though their assimilation efficiency ranges from 42 to 97%. High ash content of food organisms deviates the energy extraction efficiency in Pyrrhosoma and the aquatic dipteran herbivore Hedriodiscus.
