Various shoppers are likely to have various metabolic assimilation efficiencies inside their diet plans. Each individual trophic amount transforms Electrical power into biomass. Electrical power movement diagrams illustrate the premiums and effectiveness of transfer from just one trophic stage into A further and up with the hierarchy.[37][38]
