Question

Use the following formula to find the efficiency of energy transfer between the harbor seal (2,500 Kcal) and a polar bear (375 Kcal).
(Energy level transfered to next level)
× 100

(Total energy input)


O 15%

O 10%

O 20%

O 12%

Answer 1

Efficiency = (375 ÷ 2500) × 100 = 0.15 × 100 = 15%.

Answer: 15%
