About what percentage of the energy at one trophic level is transferred to the next level?
Answer and explanation
Correct answer: B. About 10 percent
- Step 1: Most energy is lost as heat in respiration. Step 2. About a tenth is stored in the tissue of the next level. Answer: about 10 percent. Why not the others: Transfer efficiencies of 50 percent, 25 percent, or 90 percent vastly exceed typical thermodynamic ecological transfer rates, as roughly 90 percent of energy is lost as metabolic heat between trophic levels.
