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.
Biomass pyramids show how much biomass is present in the organisms at each trophic level. A pyramid of numbers does not deal with living organisms. Source: chacha.com This, again, is my brainless answer! However, please take it seriously, for I found it in a real website this time. -_-
a pyramid of biomass is better than a pyramid of numbers because when you compare masses it gives us a better idea of the amount of energy that is avaliable at each trophic level. in a pyramid of biomass it shows the amount of energy that is lost through each step. this is the amount each trophic level decreases in comparrison to the previous.
The pyramid of biomass use the biomass and the number pyraid use the number of organisms - there is not much difference - don't get confused with it cause lots of people do.
The higher an organism is in the energy pryamid the less energy. the lower the organism`s posittion in the pyramid more energy
The 3 Types of Food Pyramids: Energy Pyramid Pyramid of Biomass Pyramid of Numbers
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 pyramid of biomass shows how much energy the organism on a food chain is getting from its food.
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.

== == Of the trophic levels of the ecological pyramid, there are three ways to describe the flow of energy in food chains. Numbers, energy and biomass. See the related link for more information.

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.
its not
biomass , you put it in a pyramid, so a pyramid of biomass.
Energy flux pyramidBiomass pyramidNumbers pyramid (the numerical value of the organisms in each trofic level)The pyramid of numbers and the pyramid of biomass are two kinds of ecological pyramids. Another is the pyramid of energy.

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.
Pyramids of Numbers show the numbers of species involved in a simple food chain. The problem with pyramids of Numbers is that in some events the pyramid is not pyramid shaped. For example, When using aphids and tomato plants as an example, there will be hundreds of aphids feeding on the tomato plant, giving the pyramid an inverse-pyramid shape. Pyramids of Biomass, however, do not take into account the numbers involved, but rather the mass. This is not only sometimes of a higher scientific value, but in most cases this will form a pyramid.
