Quizplus · Accepted Answer

All of the above factors can reduce the efficiency of energy transfer between trophic levels. Lack of availability of some biomass means that not all of the primary producers are consumed by herbivores, resulting in less energy being available for the next trophic level. Heat loss is a natural consequence of energy transfer as organisms generate heat during metabolic processes, and this heat is lost to the environment. Indigestibility of some biomass means that some food may not be fully broken down or absorbed, resulting in less energy being available for the consuming organism and reduced efficiency of energy transfer.
