Biomass at the fourth trophic level is approximately ten times smaller than biomass at the third trophic level.
Biomass is the total amount of organic matter present in any trophic level.
Biomass pyramid
Not all organisms have the same mass. Consider 1 whale versus 5,000 plankton - the whale has much greater mass, but only 0.1% of the total number of organisms. When you compare mass, you get a better idea of how much energy is actually available at that trophic level. Basically, they are better to understand.
Ecological pyramids show the relative amount of energy or biomass stored at each trophic level in a food web. They illustrate the decrease in energy or biomass as it moves up the trophic levels due to inefficiencies in energy transfer.
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.

BIOMASS
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.

The total amount of living tissue within a given trophic level is called biomass. Biomass represents the combined weight of all living organisms within that specific trophic level. It is an important measure of the energy available at each level of a food chain or food web. Biomass can be quantified in terms of grams, kilograms, or any other unit of mass.

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.
