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.
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.
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 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.

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.
The ecological pyramid of biomass and the pyramid of numbers both illustrate the structure of a coniferous forest ecosystem but focus on different aspects. The pyramid of biomass represents the total mass of living organisms at each trophic level, typically showing a larger base of producers (like trees) and diminishing biomass as you move up to herbivores and carnivores. In contrast, the pyramid of numbers counts the individual organisms at each level, which can sometimes appear inverted, particularly if a single tree supports many herbivores. Both pyramids highlight the relationships between different trophic levels, but the pyramid of biomass gives a clearer picture of energy transfer and ecosystem productivity.
The ecological pyramid is basically the food chain. So, the producers (plants) are at the bottom, then herbivores (plant eaters), then above them are the omnivores or carnivores, and then the most powerful and top of the food chain animals are at the top of the pyramid.
