Correct answers:
- Metabolic processes consume significant energy
- Only 10% of energy transfers between levels
- Energy decreases at each trophic level
Brief explanation: Energy is lost at each trophic transfer (mostly as heat through metabolism and waste), so only about ~10% is passed on to the next level. This progressive loss causes the pyramid shape (less usable energy available at higher levels).
