- A A symmetrical bell-shaped curve plotted across all the trophic levels present
- B Pyramid of energy (decreasing from producers to top consumers)
- C A perfect circle connecting all of the trophic levels together in sequence
- D A flat, unchanging line plotted consistently across all trophic levels present
Correct answer: B. Pyramid of energy (decreasing from producers to top consumers)
Explanation: Pyramid of energy: energy decreases at each successive trophic level. Only ~10% of energy is transferred upward (10% law).
