Answer 1

To find the efficiency of energy transfer between the harbor seal and the polar bear using the Ten Percent Rule, we can use the formula for efficiency:

\[
\text{Efficiency} = \left( \frac{\text{Energy level transferred to the next level}}{\text{Total energy input}} \right) \times 100
\]

In this case:
- Energy level transferred to the next level (polar bear) = 375 Kcal
- Total energy input (harbor seal) = 2500 Kcal

Now, plugging in the values:

\[
\text{Efficiency} = \left( \frac{375 \text{ Kcal}}{2500 \text{ Kcal}} \right) \times 100
\]

Calculating the fraction:

\[
\frac{375}{2500} = 0.15
\]

Now converting this to a percentage:

\[
0.15 \times 100 = 15\%
\]

So, the efficiency of energy transfer between the harbor seal and the polar bear is **15%**.
