Energy transfer between trophic levels is inefficient. Organisms use most of the energy they consume for their own life processes, and a large portion is lost as heat. Only a small fraction is converted into biomass and available for consumption by the next trophic level, leading to a reduction in energy at each step up the food chain.
Statement : Energy flow in a food chain reduces at each trophic level. Reason : At each trophic level energy is lost because organisms use them for their survival, growth and development.
