Omnivore
An organism that eats both plant and animal matter. Omnivory describes a feeding pattern, not a fixed taxonomic group.
Digestion: The process by which organisms break food into absorbable molecules. Omnivores rely on digestive processes that can handle nutrients from both plants and animals.
Food web: A network of feeding relationships among organisms in an ecosystem. An omnivore can connect plant-based and animal-based pathways in the same food web.
Herbivore: An organism that obtains food primarily from plants or other photosynthetic organisms. Herbivory lacks the regular animal-food component that defines omnivory.
Brown bear: A large bear species native to parts of Eurasia and North America. Brown bears combine plant foods, insects, fish, and other animals in diets that vary by place and season.
Digestive system: The organs and tissues that take in food, digest it, absorb nutrients, and eliminate waste. Its structure shapes which plant and animal foods an omnivore can use.
Trophic level: A position in a food chain or web defined by an organism's feeding relationships. Omnivores may occupy different trophic positions depending on what they eat.
Carnivore: An organism that obtains food primarily by consuming other animals. Carnivory contrasts with the mixed plant-and-animal diet of omnivores.
Wild boar: A widespread pig species native to Eurasia and North Africa and introduced elsewhere. Wild boars forage on roots, fruits, invertebrates, and small animals.
Dentition: The number, arrangement, and types of teeth in an organism. Omnivores often combine teeth suited to processing varied food textures.
Seed dispersal: The movement of seeds away from the parent plant by physical or biological means. Fruit-eating omnivores can disperse seeds while feeding.
