Why are there generally a maximum of five trophic levels?
It's far easier to draw a pyramid that way.
Because energy is lost at each level, there isn't enough energy left to support any more consumers.
Generally a top predator is so fierce it has no predators and therefore can rule the top trophic level without fear.

BTW the word after quaternary is quinary (always read all the options in multiple choice questions)
