A biomass pyramid differs by showing the total mass of living organisms at each trophic level within an ecosystem. Unlike energy pyramids that illustrate energy flow, biomass pyramids emphasize the amount of organic material, measured in grams or kilograms, present at each level. Typically, the biomass decreases as you move up the trophic levels, reflecting the energy lost at each stage due to metabolic processes and inefficiencies in energy transfer. This representation highlights the relative abundance and productivity of different levels of the food chain.
