What typically happens to the biomass as you move up the trophic levels in an energy pyramid?

As you progress up the trophic levels in an energy pyramid, the biomass typically decreases at each level. This phenomenon occurs due to the inefficiency of energy transfer between trophic levels. Only about 10% of the energy from one level is transferred to the next, while the remaining energy is lost mainly as heat through metabolic processes, including respiration and movement. As a result, there is less biomass available to support higher trophic levels. This decrease in biomass is what supports the overall structure of ecosystems, where fewer top predators can be sustained compared to lower-level producers and consumers.
