In a typical food pyramid, energy decreases as you move up the trophic levels. The general rule of thumb is that only about 10% of the energy is transferred from one trophic level to the next.
Starting with the producers (such as plants), we have 100,000 kJ of energy available.
1. **Producers to Primary Consumers:**
- Energy available = 100,000 kJ × 0.10 = 10,000 kJ for primary consumers.
2. **Primary Consumers to Secondary Consumers:**
- Energy available = 10,000 kJ × 0.10 = 1,000 kJ for secondary consumers.
Therefore, the amount of energy available to the secondary consumers is **1,000 kJ**.
