A pyramid of biomass is a graphical representation of biomass present in a unit area of various trophic levels. It shows the relationship between biomass and trophic level quantifying the biomass available in each trophic level of an energy community at a given time.
A biomass pyramid shows the amount of living biological material (biomass) present at each trophic level of an ecosystem. It is usually represented as a triangular diagram, with the base of the pyramid representing the primary producers (e.g. plants) that form the foundation of the food chain.
Make hypotheses about the relationship between biomass pyramids and pyramids of productivity, and test those hypotheses with data. Explain the role of abiotic factors, such as sunlight, on trophic biomass pyramids.
An ecological pyramid (also trophic pyramid, Eltonian pyramid, energy pyramid, or sometimes food pyramid) is a graphical representation designed to show the biomass or bioproductivity at each trophic level in an ecosystem.
An ecological pyramid is a graphical representation that shows, for a given ecosystem, the relationship between biomass or biological productivity and trophic levels. A biomass pyramid shows the amount of biomass at each trophic level.
A pyramid of biomass measures the total amount of biomass in each trophic level of an ecosystem instead of using the total population of every species. Biomass pyramids can be upright or inverted, depending on the ecosystem.
A biomass pyramid is the representation of total living biomass or organic matter present at different trophic levels in an ecosystem. Biomass is calculated as the mass of living organisms present at each trophic level in a given sample size.
