What defines an omnivore?

An omnivore is defined as an organism that has the ability to consume and derive energy from both plant and animal matter. This dietary flexibility allows omnivores to thrive in a variety of environments and to adapt to changing food availability. By eating both plants and animals, omnivores can take advantage of a broader range of nutrients compared to those that specialize in either plant or animal consumption alone. This can include a variety of foods such as fruits, vegetables, grains, meat, and fish, making their diets diverse and adaptable. This characteristic plays a vital role in the ecosystems where they exist, as they can help maintain balance between different trophic levels.
