Decrease in energy at higher trophic levels Explanation - Since only 10 percent of energy available at a trophic level is passed on to the next trophic level and rest energy is lost as heat, very little usable energy remains available after four trophic levels. So, decrease in energy at higher trophic levels limits the number of trophic levels in a food chain.
