pyramids of biomass

• pyramids of biomass show the relative mass of each tropic level
• there's less energy and less biomass every time you move up a stage in a food chain
• there are usually fewer organisms moving up levels
• each bar on a pyramid of biomass shows the relative mass of a living material at a trophic level
• the bottom level always represents the producer
• the second bar from the bottom is the primary consumer, then the secondary consumer
