Question

When energy is transferred from one trophic level to the next, about 90% of the energy is lost. If plants produce 1,000 kcal of energy, how much of the energy is passed to the next trophic level?

Answer 1

100 kcal of energy is passed to the next trophic level

Answer 2

A pyramid of energy represents how much energy, initially from the sun, is retained or stored in the form of new biomass at each trophic level in an ecosystem. Typically, about 10% of the energy is transferred from one trophic level to the next, thus preventing a large number of trophic levels.
