10 kJ

Answer 1

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

In the food pyramid you provided:

1. Producers (Grass): 100,000 kJ
2. Primary Consumers (Mice): Approximately 10% of 100,000 kJ = 10,000 kJ
3. Secondary Consumers (Snakes): Approximately 10% of 10,000 kJ = 1,000 kJ
4. Tertiary Consumers (Hawks): Approximately 10% of 1,000 kJ = 100 kJ

Thus, the energy available to the secondary consumers (Snakes) is 1,000 kJ.

So the correct response is 1,000 kJ.
