A pyramid of biomass shows the total biomass of the organisms involved at each trophic level of an ecosystem. These pyramids are not necessarily upright. There can be lower amounts of biomass at the bottom of the pyramid if the rate of primary production per unit biomass is high.

$Explanation$ →Always upright as energy is lost as heat at each step. It reflects more accurately the law of thermodynamics, with loss of energy being depicted at each transfer to another trophic level, hence the pyramid is alwasys right.An ecological pyramid is a graphical representation of the relationship between different organisms in an ecosystem. Each of the bars that make up the pyramid represents a different trophic level, and their order, which is based on who eats whom, represents the flow of energy.
