Answer 1

In a typical food pyramid, energy decreases by a factor of about 10 as it moves up each trophic level.

If 100,000 kJ of energy is available to the producers (the first trophic level), the energy available to the primary consumers (the second trophic level) would be:

100,000 kJ / 10 = 10,000 kJ

Then, for the secondary consumers (the third trophic level):

10,000 kJ / 10 = 1,000 kJ

Therefore, the amount of energy available to the secondary consumers is 1,000 kJ.
