Answer: 50 J

By Lindeman’s 10% law, only about 10% of the energy at one trophic level passes to the next. Taking 5000 J at the producer level: herbivores (primary consumers) get 10% of 5000 J = 500 J, and carnivores (secondary consumers) get 10% of 500 J = 50 J.

Producers (5000 J) → herbivores (500 J) → carnivores (50 J).
