Relative abundance of weight?

If a hawk eats a fish and does not acquire all the energy in the fish's body because of the second law of thermodynamics then what implications would have a relative abundance by weight of predators and their prey?

I understand the laws of thermodynamics this question is just very confusing for me. I was wondering if anyone had any suggestions.



The total weight of the prey eatten is greater than the weight of the predator. What does this mean for the total weight of bacteria or photoplanton in the world, according to the food heirarchy?
