To find the efficiency of energy transfer between the harbor seal and the polar bear, we first need to calculate the energy level transferred to the polar bear:
Energy level transferred to polar bear = 375 Kcal
Next, we need to calculate the total energy input:
Total energy input = Energy level transferred to polar bear + Initial energy level of the harbor seal
Total energy input = 375 Kcal + 2500 Kcal
Total energy input = 2875 Kcal
Now, we can calculate the efficiency of energy transfer using the formula provided:
Efficiency = (Energy level transferred to next level / Total energy input) * 100
Efficiency = (375 Kcal / 2875 Kcal) * 100
Efficiency = (0.13) * 100
Efficiency = 13%
Therefore, the efficiency of energy transfer between the harbor seal and the polar bear is 13%.
Use the following formula to find the efficiency of energy transfer between the harbor seal (2,500 Kcal) and a polar bear (375 Kcal).
