28,000 kJ

Answer 1

3,200 kK

Explanation:

Typically, only about 10% of the energy available at one trophic level is transferred to the next trophic level. This is known as the 10% rule, and it means that herbivores will only be able to incorporate about 10% of the energy available in the big bluestem grasses.

Therefore:

32,000 kJ x 0.10 = 3,200 kJ
