What is the primary diet of omnivores composed of?

The primary diet of omnivores is composed of both plants and animals, which reflects their ability to consume a variety of food sources. This dietary flexibility allows omnivores to thrive in diverse environments by taking advantage of different types of available nutrition. Their adaptability is a significant evolutionary advantage, enabling them to fill various ecological roles and survive in changing conditions.

Omnivores utilize plant materials such as fruits, vegetables, and grains for carbohydrates, as well as animal-based products like meat and fish for protein and fats. This mixed diet helps ensure they obtain a wide range of nutrients necessary for their survival and health. In contrast, the other options focus solely on one food source type, which does not accurately represent the nature of omnivores.
