Final answer:

Energy loss between trophic levels limits food chain length due to the second law of thermodynamics.


Explanation:

One major factor that limits the length of food chains is energy. Energy is lost as heat between each trophic level due to the second law of thermodynamics. After multiple trophic energy transfers, the remaining energy may not be sufficient to support higher trophic levels due to these losses.
