Which of the following correctly defines an omnivore?

An omnivore is correctly defined as an animal that eats both plant and animal material. This classification indicates a versatile diet, which allows omnivores to consume a wide range of food sources. This adaptability is beneficial for survival, particularly in environments where food availability can vary. Omnivores play a crucial role in ecosystems as they help control populations of plants and animals, thus maintaining a balance within their habitats.

The other choices illustrate different types of dietary habits: animals that eat only plants are classified as herbivores, while those that eat only other animals are carnivores. Additionally, a decomposer refers to organisms, often microbes or fungi, that break down dead organic material, which is distinctly different from the feeding habits seen in omnivores. Understanding these definitions highlights the diversity of dietary strategies in the animal kingdom.
