Is it possible that the food chains have more than six steps? Support your answer with reasons.
No, it is not possible that the food chains have more than six trophic levels. This is because only 10% energy is passed on to the next trophic level and 90% of it is lost. Since only 10 % of the energy at a trophic level is available at each successive level, thus , it a food chain cannot support more than six steps, as energy available to the top level will not be sufficient to sustain life.
