omnivorycapable

Omnivorycapable is a term used to describe organisms that have the ability to obtain energy and nutrients from both animal and plant matter, displaying dietary flexibility that allows them to use multiple trophic resources. The expression is not a formal taxonomic category but a descriptive label often employed in ecological discussions to emphasize plasticity in foraging strategies and feeding ecology.

In practice, omnivorycapable species include many mammals, birds, fish, and invertebrates that routinely mix diets. Examples commonly cited are humans, bears, raccoons, pigs, crows, and many rodent species, which can switch among fruits, seeds, foliage, invertebrates, and vertebrate prey depending on availability. Some fish and crustaceans also show omnivorous feeding patterns, consuming a range of animal and plant-derived foods. The criterion is ecological rather than strictly physiological: what matters is demonstrated capacity to utilize diverse food resources rather than a single specialized diet.

Ecological significance centers on resilience and niche breadth. Omnivory-capable organisms can adapt to resource fluctuations, potentially sustaining populations during shortages of one resource by exploiting alternatives. This flexibility may come with trade-offs, such as higher digestive enzyme diversity requirements or less optimal efficiency on any single food type, compared with specialists.

Terminology notes: omnivorycapable highlights potential or observed versatility rather than a formal classification. In formal contexts, researchers may simply describe an organism as omnivorous or opportunistic, with the term serving as a concise shorthand in syntheses or discussions of dietary plasticity.
