onivorous

Onivorous is a term used to describe an organism that consumes both plants and animals. This dietary strategy, also known as omnivory, is common across a wide range of species, from insects and birds to mammals. Organisms that are onivorous have a digestive system adapted to process both plant and animal matter, often possessing a combination of teeth and digestive enzymes suited for this diverse diet.

The flexibility of an onivorous diet can be a significant advantage for survival. It allows these animals to exploit a broader range of food resources, which can be particularly beneficial in environments where the availability of specific food sources fluctuates. For example, an onivorous animal might feed on fruits and seeds when they are in season, but also consume insects or small vertebrates when plant matter is scarce. This adaptability contributes to their widespread distribution and ecological success.

Examples of onivorous animals include humans, bears, pigs, raccoons, and many species of birds like crows and chickens. The specific balance of plant and animal matter in an onivorous diet can vary greatly depending on the species and its environment. Some onivores may lean more heavily towards a plant-based diet, while others may consume a more equal proportion of both. This dietary plasticity is a defining characteristic of omnivory.
