How would a pyramid reflecting biomass be similar to or different from an energy pyramid?

A biomass pyramid looks like an energy pyramid, in that the largest biomass is contained in the producer level, and the least biomass is contained in the level of the highest order consumer. Basically, as you move up the energy pyramid, there is less energy available to support the biomass at each subsequent level.

Most ecosystems can be visualized as a pyramid with many organisms in the lowest trophic levels and only a few individuals at the top Give an example of an inverted numbers pyramid?

An example of an inverted numbers pyramid can be seen in a parasite-host relationship, where a single host may support a large population of parasites. In this case, the number of individuals in the higher trophic level (parasites) exceeds the number of individuals in the lower trophic level (host).


What are organisms in the lowest trophic level of an ecosystem?

Plants are in the lowest trophic level of an ecosystem. Their level is the lowest because the needs of plants are the least complex compared to the other organisms present in an ecosystem.
