title: Ubiquity of omnivores in natural ecosystems.
abstract: Evolutionary ubiquity of omnivores in natural food webs derives from the measurement dynamics of intra and inter trophic levels. It is recognized that inter-level communication for the maintenance of energy flow continuity takes longer than intra-level communication does. Although the collapse of food webs due to depletion of the lower levels is inevitable according to the measurement dynamics; participation of omnivores could extend the evolutionary durability of the food webs.
