In a typical ecological model (such as a food pyramid), energy transfer between trophic levels is generally understood to follow the 10% rule, which states that approximately 10% of the energy from one trophic level is passed on to the next.

If we start with producers having 100% of the energy:

- Primary consumers (level 1) would receive about 10% of the energy from producers, so they would have 10%.
- Secondary consumers (level 2) would receive about 10% of the energy from primary consumers, so they would have 1%.
- Tertiary consumers (level 3), or third level consumers, would then receive about 10% of the energy from secondary consumers, resulting in about 0.1%.

Therefore, a third level consumer has **0.10%** of the original energy produced by the producers.
