Question

Quizplus · Accepted Answer

Trophic efficiency is defined as the percentage of production transferred from one trophic level to the next. It represents the efficiency with which energy and biomass are transferred from one level to another in a food chain. It is typically around 10% for most ecosystems, meaning that only about 10% of the energy stored in each trophic level is passed on to the next level. Therefore, choice B is the correct answer. A, C, D, and E are incorrect statements.
