Answer 1

In an ecosystem, energy transfer between trophic levels is generally considered to follow the 10% rule, where only about 10% of the energy is transferred from one level to the next. This means that if producers generate 100% of the energy, tertiary consumers would receive approximately 0.1% of that energy by the time it reaches them (after accounting for losses at multiple levels).

So, the correct answer is:

**0.1%**
