How do I Calculate the productivity P in KJ?

I: Intake
F: Feces
A: Assimilation (Assimilation=Intake-Feces)
R: Respiration
P: Production (Production=Assimmilation-Respiration and Production = Intake - Feces - Respiration)


A certain animal has a production efficiency (P/A) of 2%, while his assimilation efficiency is 80%.

1. How do I Calculate the productivity P in KJ if this animal has an energy content of 100 KJ.

2. What amount of energy of this animal will benefit a higher trophic level?
