Which energy pyramid cannot be inverted? a. pyramid of numbers b. pyramid of biomass c. pyramid of energy d. all can be inverted

The correct option is C.

The pyramid of numbers and the pyramid of biomass can be inverted but the pyramid of energy can not be treated in the same way. The pyramid of energy is a graphical representation of the flow of energy in the ecosystem. The ultimate source of energy in the ecosystem is the sun. The plants, which are called the producers use the energy of the sun to produce their own foods. It is the energy that the primary consumers obtained from the producers that will be pass on to others in the ecosystem. Thus, the value of the energy reduce gradually as it is passed from one level to another.
