food chains generally consist of only three or four trophic levels why is it so
Answers
Answer:
Why food chains generally consist of three or four steps only? Since so little energy is available for the next level of consumers, and for this reason food chains generally consist of only three or four steps. The loss of energy at each step is so great that very little usable energy remains after four trophic levels.
