The correct answer is 15%.
To find the efficiency of energy transfer, you need to divide the energy level transferred to the next level by the total energy input and then multiply it by 100 to get the percentage.
In this case, the energy level transferred to the next level is 375 Kcal (which is the energy received by the polar bear), and the total energy input is 2,500 Kcal (which is the energy initially available in the harbor seal).
So, the efficiency of energy transfer between the harbor seal and the polar bear is:
(375 Kcal / 2,500 Kcal) x 100 = 0.15 x 100 = 15%
