Show ALL working.

To calculate the percentage of energy that is passed on from the grasshopper to the blue jay, we first need to identify the amount of energy at each level and then determine the energy transfer from the grasshopper to the blue jay. 1. **Identifying Energy Values**: - Energy from grass (producers) = 97,000 kJ - Energy received by the grasshopper (primary consumer) = 600 kJ - Energy received by the blue jay (secondary consumer) = 50 kJ 2. **Finding Energy Passed from Grasshopper to Blue Jay**: The blue jay receives 50 kJ from the grasshopper, which had 600 kJ available. 3. **Calculating the Percentage**: To find the percentage of the energy passed from the grasshopper to the blue jay, we use the formula: \[ \text{Percentage transferred} = \left( \frac{\text{Energy received by blue jay}}{\text{Energy from grasshopper}} \right) \times 100 \] Plugging in the values we have: \[ \text{Percentage transferred} = \left( \frac{50 \text{ kJ}}{600 \text{ kJ}} \right) \times 100 \] Now performing the calculation: \[ \text{Percentage transferred} = \left( \frac{50}{600} \right) \times 100 = \frac{50 \times 100}{600} \] \[ \text{Percentage transferred} = \frac{5000}{600} \approx 8.33\% \] So, the percentage of energy that is passed on from the grasshopper to the blue jay is approximately **8.33%**.
