Explanation:

In a food chain, energy decreases at each trophic level. Primary consumers eat producers, secondary eat primary, tertiary eat secondary, and quaternary eat tertiary. Each level loses energy (e.g., through respiration, waste), so the highest (quaternary) has the least energy supply.

Answer:

D. quaternary
