The term "pyramid of numbers" is derived from the visual representation of the relationship between different trophic levels in an ecosystem. In this graphical representation, the number of organisms at each trophic level is depicted as a pyramid, with the primary producers forming the base and the top predators at the apex. This structure resembles a pyramid due to the decreasing number of organisms at each successive trophic level, reflecting the energy transfer and biomass distribution within the ecosystem.
Depends on the pyramid. A pyramid with a square (or quadrilateral) base would indeed have 8 edges, but a pyramid can have any other polygon as a base.Depends on the pyramid.

Pentagonal pyramid because a pentagon has five sides and then you have the base.
A square pyramid has 1 more vertex than a triangular pyramid. A square pyramid has 5 vertices, and a triangular pyramid has 4 vertices.

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.
The diagram that shows trophic levels on blocks is called a pyramid of energy or ecological pyramid. It visually represents the flow of energy through different trophic levels in an ecosystem, with each block indicating the amount of energy available at each level. Typically, producers (plants) are at the base of the pyramid, followed by herbivores, then primary and secondary carnivores at higher levels.
The first of the four, is the ecological pyramid. It shows the number of organisms in each of the trophic levels in an ecosystem. At the base of the levels are the producers and at the top of the pyramid are the final consumers. The second is the number pyramid. This also shows the number of organisms in each of the trophic levels but it does not take into consideration the size of each of the organism in the levels. This pyramid has four levels, starting from the bottom is the total number of producers, then the total number of herbivores, third the total number of small carnivores, and finally the total number of large carnivores. The third pyramid is the biomass pyramid. This pyramid is an indication of the total mass of organisms in the trophic levels. There are three levels of biomass in this pyramid. These are producers ( 470.0 g/m2), then herbivores (0.6 g/m2), and last the carnivores ( 0.1 g/m2). And it is possible for the second level to be greater than the third. Last, is the energy pyramid which indicates the total amount of energy that is in the trophic levels. It also is able to show the loss of energy between the trophic levels. The four levels in this pyramid are Producers, Primary consumers, Secondary consumers and at the top are the Tertiary consumers. As energy passes between the levels, such as from producers to primary consumers, much of the energy is lost due to waste and the conversion to heat energy.

there can be any number of trophic levels, but usually 4-5
If the organisms in a food chain are arranged according to trophic levels, they form a pyramid, with a broad base representing the primary producers and usually only a few individuals in the highest part of the pyramid. Also known as a "pyramid of numbers," an ecological pyramid is a way of describing the distribution of energy, biomass, or individuals among the different levels of ecosystem structure.
The pyramid of energy always remains upright because energy diminishes as it moves up trophic levels in an ecosystem. This is because energy is lost as heat during each transfer between trophic levels, leading to a decrease in available energy for higher trophic levels.
It was a pyramid of brick and earth rising 5 levels high.
