Eagles-q snakes-r mice-s grain-t which trophic level contains the smallest percentage of total stored energy?

Answer is eagles.

As we go up the trophic levels the amount of stored energy decreases because a lot of energy is lost(as heat, “wasted energy”).
So the tertiary consumers(hughest trophic level) get the least amount of energy and have the least amount of biomass. (Also see attachment)
