Trophic levels
Explanation:
Decrease in energy at higher trophic levels limits the number of trophic levels in a food chain. When the number of links keep increasing, the amount of energy available decreases, as only 10% of energy gets transferred from one trophic level to the next.
The different feeding positions in a food chain or web are called trophic levels. Generally, there are no more than four trophic levels because energy and biomass decrease from lower to higher levels.
