which of the follwing pyramids is not used in ecology? pyramid of
Answer Details
The pyramid that is not used in ecology is the pyramid of organisms. This is because the other three options - energy, numbers, and biomass - are the three main types of ecological pyramids that are commonly used to describe different aspects of ecosystems.
The pyramid of energy shows the flow of energy through an ecosystem and how much energy is transferred from one trophic level to another. It typically has a triangular shape, with the primary producers at the base and the top predators at the apex.
The pyramid of numbers shows the relative number of individual organisms at each trophic level of an ecosystem. This pyramid can have different shapes, depending on the ecosystem being studied.
The pyramid of biomass shows the total amount of living organic matter, or biomass, at each trophic level of an ecosystem. This pyramid can also have different shapes, depending on the ecosystem being studied.
In contrast, the pyramid of organisms is not commonly used in ecology because it is difficult to measure and does not provide as much information about the structure and function of an ecosystem as the other three types of pyramids.
