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.
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.
A pyramid of biomass shows how much energy the organism on a food chain is getting from its food.
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.
Energy is lost as it moves up the energy pyramid due to inefficiencies in energy transfer, metabolism, and heat loss from organisms. In the biomass pyramid, energy is lost through respiration, growth, and waste production. In the numbers pyramid, energy is lost as it moves up due to population control mechanisms, such as predation and competition.
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 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. -_-

== == 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 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.
