In an ecological energy pyramid, energy transfer between trophic levels is inefficient. Typically, only about 10% of the energy is passed from one trophic level to the next, known as the 10% rule.
1. Producers generate 100% of the energy.
2. Primary consumers (herbivores) receive approximately 10% of that energy, which is 10% of 100%, or 10%.
3. Secondary consumers (carnivores that eat primary consumers) receive approximately 10% of that energy, which is 10% of 10%, or 1%.
4. Tertiary consumers will then receive 10% of that energy, which is 10% of 1%, or 0.1%.
So, by the time the energy reaches tertiary consumers, only about 0.1% of the original energy from producers is left.
Therefore, the correct answer is:
**0.1%**
1. Producers generate 100% of the energy.
2. Primary consumers (herbivores) receive approximately 10% of that energy, which is 10% of 100%, or 10%.
3. Secondary consumers (carnivores that eat primary consumers) receive approximately 10% of that energy, which is 10% of 10%, or 1%.
4. Tertiary consumers will then receive 10% of that energy, which is 10% of 1%, or 0.1%.
So, by the time the energy reaches tertiary consumers, only about 0.1% of the original energy from producers is left.
Therefore, the correct answer is:
**0.1%**
