Answer: Pyramid of energy (decreasing from producers to top consumers).
- 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).
Energy pyramid showing a simple food chain (producer to herbivore to carnivore) with energy decreasing roughly tenfold at each trophic level.
