Which of the following limits the number of trophic levels in a food chain?
A. Insufficient food supply from producer level

B. Decrease in energy at higher trophic levels

C. Increase in the number of organisms at higher trophic levels

D. Accumulation of harmful chemicals at higher trophic levels

Since only 10% of energy is transferred at each trophic level, the higher trophic level get very low amount of energy which is not sufficient for the organisms to sustain life. So, the trophic level gets restricted to amount of energy available at which the organisms at that trophic level can sustain life.
