a biomass pyramid
A pyramid of numbers will only tell you the amount of organisms at each trophic level. A Biomass pyramid ignores the amount of organisms in favour of their biomass (dry weight) which in turn represents the amount of energy available at each trophic level.
Biomass pyramid
On an ecological pyramid or in a food chain, typically, the highest trophic levels have the least amount of energy from the sun available for the next highest level. In a typical food chain, this would be the tertiary consumer level.
The number is limited by the amount of energy lost at each trophic level. Most cannot exceed 5.

A biomass pyramid looks like an energy pyramid, in that the largest biomass is contained in the producer level, and the least biomass is contained in the level of the highest order consumer. Basically, as you move up the energy pyramid, there is less energy available to support the biomass at each subsequent level.
A biomass pyramid illustrates the amount of organic material, or biomass, present at each trophic level in an ecosystem. Typically, it shows that producers (like plants) have the highest biomass, followed by primary consumers (herbivores), secondary consumers (carnivores), and so on, with each successive level having less biomass. This structure highlights the energy flow and efficiency within an ecosystem, as energy is lost at each trophic level due to metabolic processes. Ultimately, the pyramid shape emphasizes the diminishing biomass and energy available to higher trophic levels.
The diagram that shows trophic levels on blocks is called a pyramid of energy or ecological pyramid. It visually represents the flow of energy through different trophic levels in an ecosystem, with each block indicating the amount of energy available at each level. Typically, producers (plants) are at the base of the pyramid, followed by herbivores, then primary and secondary carnivores at higher levels.
An ecological pyramid is simply a graphical representation of the relationship at each trophic level in a particular ecosystem. There are three types of ecological pyramids: of numbers, of energy, and of biomass. For example the pyramid of numbers is a representation of the number of organisms in each trophic level, with herbivores at the bottom as primary consumers, followed by first level carnivores and so on.
