To find the efficiency of energy transfer between the harbor seal and the polar bear using the formula provided, we can plug in the values as follows:
- Energy level transferred to the next level (polar bear): 375 Kcal (energy received by the polar bear)
- Total energy input (harbor seal): 2,500 Kcal (energy source before transfer)
Now, applying the formula:
Substituting in the numbers:
Calculating the fraction:
Now, multiply by 100 to get the efficiency percentage:
Thus, the efficiency of energy transfer between the harbor seal and the polar bear is 15%.
