Answer 1

In a food pyramid, energy transfer between trophic levels typically follows the 10% rule, which states that only about 10% of the energy from one level is passed on to the next level.

Given that there is 100,000 kJ of energy available to the producers (grass), we can calculate the energy available to the secondary consumers (snakes) as follows:

1. Energy available to primary consumers (mice) from producers: \[ 100,000 \text{ kJ} \times 0.10 = 10,000 \text{ kJ} \]

2. Energy available to secondary consumers (snakes) from primary consumers: \[ 10,000 \text{ kJ} \times 0.10 = 1,000 \text{ kJ} \]

Therefore, the energy available to the secondary consumers (snakes) is 1,000 kJ.

So the correct response is: 1,000 kJ.
