Pyramids of Numbers and Biomass
Pyramids of numbers and energyOmnivoryTrophic position and categoriesWidespread omnivory in aquatic food webs has been recognized to compromise interpretation of Lindeman's "pyramid of energy" wherein organism biomass is constrained into rigidly delineated trophic levels. A compilation of global, pre-1997...

The existence of a pyramidal trophic structure in ecosystems has become one of the first principles of ecology. Evidence for this may be found in most general textbooks of ecology, which present trophic pyramids in terms of numbers, biomass, or energy content of organisms (e.g., Odum 1973)....
In ecological communities consumers (excluding parasites and parasitoids) are in general larger and less numerous than their resource. This results in a well-known observation known as ‘Eltonian pyramids’ or the ‘pyramid of numbers’, and metabolic arguments suggest that this pattern is independent...
