D Correct answer
Explanation

Each trophic level has limited total biomass because energy is lost at each transfer (10% rule). This means higher trophic levels can support less total biomass. Deer are herbivores, lions are heterotrophs not autotrophs, and predators typically have fewer numbers than prey (not greater).
