Final answer:
The length of a food chain is NOT determined by the number of links between trophic consumers.
Step-by-step explanation:
The length of a food chain is determined by the number of links between trophic consumers.
FALSE.
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. Thus, after a limited number of trophic energy transfers, the amount of energy remaining in the food chain may not be great enough to support viable populations at yet a higher trophic level.
