• please choose an answer

Explanation:

Step1: Energy transfer rule

In an energy pyramid, about 10% of energy is transferred from one trophic level to the next.

Step2: Calculate for third - level consumer

Producer (100%) → First - level consumer ($100\%\times10\% = 10\%$) → Second - level consumer ($10\%\times10\%=1\%$) → Third - level consumer ($1\%\times10\% = 0.1\%$)

Answer:

0.10%
