How do scientists account for the decrease in available energy from one trophic level to the next higher trophic level?

• the energy available to the organisms at the lower trophic levels

• the energy of the sun cannot be fully exploited by producers

• the energy is stored in energy dense molecules for decomposers

• the energy is used by organisms for life functions or is lost as heat
