An energy pyramid is the best way to assess the functional roles of the trophic levels in an ecosystem. An energy pyramid depicts the amount of energy at each trophic level as well as the energy lost during each trophic level transfer. As a result, the pyramid is always upward, with a large energy base at its base. This is because, in order for the ecosystem to sustain itself, there must be more energy at lower trophic levels than there is at higher trophic levels. This allows organisms on the lower levels to not only maintain a stable population, but also to transfer energy up the pyramid.A pyramid of biomass is a graphical portrayal of biomass present in a unit of the territory of different trophic levels. In addition, it displays the linking among biomass and trophic level estimating the biomass available in each trophic degree of an energy network at a given time. A pyramid is a three-dimensional shape. A pyramid has a polygonal base and flat triangular faces, which join at a common point called the apex. A pyramid is formed by connecting the bases to an apex. Each edge of the base is connected to the apex, and forms the triangular face, called the lateral face. Ecological characteristics are the features that define the relationships that exist between living organisms and their physical environment in a defined space. They include what organisms feed on each other and what organisms play the same role in that environment. The biomass of organisms in each trophic level is measured and presented in a pyramid of biomass. It is more accurate as the organism's size is taken into account. As, a bar representing 1 tree will be largest as it has more mass than primary consumers. Because it gives us more information about trophic levels, energy transfers and feeding patterns of animal species, scientists can leverage biomass pyramids to make more educated decisions about environmental conservation efforts. Advantages of the pyramid of energy as a representation: It takes account of the rate of production over a period of time. Two species of comparable biomass may have very different life spans. Thus, a direct comparison of their total biomasses is misleading, but their productivity is directly comparable. A pyramid of biomass represents the mass of organisms at each trophic level. A pyramid of biomass is always shaped like a pyramid because the biomass always goes down from one trophic level to the next.A pyramid of energy or pyramid of productivity shows the production or turnover of biomass at each trophic level. Instead of showing a single snapshot in time, productivity pyramids show the flow of energy through the food chain.
