0.1%

100%

Answer 1

Typically, energy transfer in an ecosystem follows the 10% rule, where only about 10% of the energy from one trophic level is passed on to the next level. Therefore, by the time energy reaches tertiary consumers, it can be estimated that approximately 0.1% of the original energy produced by producers is left.

So, the correct response would be **0.1%**.
