Question

In a food chain with each feeding relationship the energy transferred from one organism to another will
Decrease
Increase
Remain constant
Be independent of the level

Answer 1

In a food chain, the energy transferred from one organism to another will **decrease** at each trophic level. This is due to the second law of thermodynamics, which states that energy transfer is not 100% efficient; some energy is lost as heat or used for metabolic processes. Typically, only about 10% of the energy from one trophic level is available to the next, leading to a decrease in energy availability as one moves up the food chain.
