In a typical energy pyramid, only about 10% of the energy from one trophic level is transferred to the next level. Therefore, if the first trophic level (producers) has 300,000 kilocalories of available energy, the energy available at the second trophic level (herbivores) would be approximately:
\[
300,000 \text{ kilocalories} \times 0.10 = 30,000 \text{ kilocalories}
\]
Then, if we apply the same 10% rule to find the energy available at the third trophic level (carnivores), we have:
\[
30,000 \text{ kilocalories} \times 0.10 = 3,000 \text{ kilocalories}
\]
Therefore, the correct amount of energy available at the third trophic level is **about 3,000 kilocalories**.
\[
300,000 \text{ kilocalories} \times 0.10 = 30,000 \text{ kilocalories}
\]
Then, if we apply the same 10% rule to find the energy available at the third trophic level (carnivores), we have:
\[
30,000 \text{ kilocalories} \times 0.10 = 3,000 \text{ kilocalories}
\]
Therefore, the correct amount of energy available at the third trophic level is **about 3,000 kilocalories**.
