Use the following formula to find the efficiency of energy transfer between the harbor seal (2,500 kcal) and a polar bear (374 Kcal)

(Energy level transfered to next level)/(Total energy input) x 100

To find the efficiency of energy transfer between the harbor seal and polar bear, we will use the following formula:

Efficiency = (Energy transferred to next level / Total energy input) x 100

Given:
Energy transferred to next level = 374 Kcal
Total energy input = 2,500 Kcal

Substituting the values into the formula:

Efficiency = (374 Kcal / 2,500 Kcal) x 100

Efficiency = (0.1496) x 100

Efficiency = 14.96%

Therefore, the efficiency of energy transfer between the harbor seal and polar bear is approximately 14.96%.
