It decreases.
Energy is lost at each transfer (respiration, heat, waste), so less energy and thus less biomass is supported at higher trophic levels (typically ~10% transfer efficiency). Note: rare exceptions (e.g., some aquatic systems) can show inverted biomass pyramids due to rapid producer turnover.
