Answer: There are three energy level in the energy pyramid. The producers have the 100% energy and the primary consumers feed on the producers and obtain 10% energy the producers have and secondary consumers feed on the primary consumers.

Primary consumers will have 475,65 kilocalories
Secondary consumers will have 4756.5 kilocalories
