If a biomass pyramid contains 400 kilograms of wheat at its base, 4 kilograms of human tissue would exist at the fourth topic level.
Biomass - the total dry weight of the organisms in a trophic levelBiomass Pyramid - a diagram showing the biomass at each trophic level of a food chainA pyramid of biomass shows energy lost in each trophic level while a pyramid of numbers shows the numbers of the organisms in each trophic level
A pyramid of biomass or a pyramid of energy can show the total mass of living tissue at each trophic level. These pyramids illustrate the decreasing amount of biomass or energy available as you move up the food chain, with producers at the base and top-level consumers at the top.
A biomass pyramid displays the total biomass at each trophic level in an ecosystem. In a typical pyramid, the biomass decreases as you move up the trophic levels, with primary producers at the base having the most biomass. In a tropical ecosystem, the biomass pyramid may be inverted due to high turnover rates and rapid growth and reproduction of organisms, leading to a larger biomass of consumers compared to producers.
Biomass pyramid
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 food web diagram best illustrates the number of trophic levels in an ecosystem. This diagram depicts the interconnected feeding relationships among various organisms in an ecosystem, clearly showing the flow of energy through different trophic levels.

Each trophic level contains one-tenth as much biomass as the level below it and ten times as much biomass as the level above it.
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 decreases as you move up the pyramid due to the loss of energy through metabolic processes and heat production at each trophic level. As energy is transferred from one trophic level to the next, only a fraction is incorporated into the biomass of the organisms, leading to a decrease in biomass as you move up the pyramid.

In an ecological pyramid, biomass represents the total mass of living organisms within each trophic level. The 90 heat rule states that only about 10% of energy is passed on from one trophic level to the next, with the rest being lost as heat. Therefore, the biomass at a particular trophic level will be ten times greater than the biomass at the next higher trophic level, reflecting the loss of energy as heat through the different trophic levels.
An ecological pyramid is a graphical representation of the trophic levels (different feeding levels) within an ecosystem. It shows the flow of energy or biomass from one trophic level to the next, with producers at the bottom and top predators at the top. There are three types: pyramid of numbers, pyramid of biomass, and pyramid of energy.
