The amount of energy decreases.
In a food chain, energy decreases as it moves up through the trophic levels due to energy loss at each level primarily through metabolic processes, heat dissipation, and inefficiency in energy transfer. Typically, only about 10% of the energy from one trophic level is transferred to the next level, leading to a decrease in available energy at higher trophic levels.
