Because of the high rate of energy loss in food chains, there are usually only 4 or 5 trophic levels in the food chain or energy pyramid. There just is not enough energy to support any additional trophic levels.

Answer:

the energy is only taken at a fraction from the previous level because of the actual predation taking lots of energy. this keeps going until the top trophic level gets less energy that in needs to survive
