Concept:A pyramid of energy always shows energy, never the number of organisms at each level.
Explanation:A pyramid of energy displays the quantity of energy available at each trophic level.
It helps in studying the efficiency of energy transfer between trophic levels.
It also allows comparisons between different ecosystems and trophic levels to be made accurately.
However, representing the number of organisms at different trophic levels is the function of a pyramid of numbers, not a pyramid of energy.
Therefore, this statement is not associated with pyramids of energy.
Answer:D. Representation of numbers of organisms at different trophic levels
