Why is the number of trophic level that can exist limited?

All sources of energy come from the sun. Autotrophs make their own energy through photosynthesis by collecting energy from the sun. When an organism (herbivore) at the next trophic level eats them they only get approximately 10% of the energy that the first organism had. When another organism eats the animal that ate the plate they only get approximately 10% of the energy of what that animal got from the previous animal. So this animal only got 1% of the energy from the sun. If more trophic levels existed they would only get 10% of this 1% so would not get enough energy (approximately 0.1%) so is why trophic levels are limited.
