Final answer:
The overall energy contained in biomass is typically highest at low trophic levels.
Step-by-step explanation:
The overall energy contained in biomass is typically highest at low trophic levels. With less energy at higher trophic levels, there are usually fewer organisms and less biomass. Biomass is the amount of organic matter present in an individual organism or in all the organisms at a given trophic level. Energy passes up a food chain or food web from lower to higher trophic levels, but only about 10 percent of the energy at one trophic level is actually passed on to the next higher trophic level.
