B) Pyramids of biomass
C) Pyramids of energy
D) Both a and b
E) None of the above

Quizplus · Accepted Answer

Pyramids of energy always have a pyramidal shape because energy is lost as it flows through trophic levels due to inefficiencies in energy transfer and metabolic processes. As a result, there is less energy available at higher trophic levels, leading to a pyramidal shape in the energy pyramid. Pyramids of number and biomass do not always have a pyramidal shape as they can be inverted or columnar depending on the ecosystem being studied.
