A producer fixes 12000 kJ of energy. The primary consumer receives 1200 kJ. What is the percentage efficiency of energy transfer?
Answer and explanation
Correct answer: D. 10 percent
- Step 1: Efficiency = energy transferred / energy available x 100. Step 2. 1200 / 12000 x 100 = 10 percent. Answer: 10 percent. Why not the others: these misplace the decimal or invert.
