omnivore
Definition
An omnivore is an organism that can derive its energy and nutrients from a variety of sources, including plants, animals, and other organisms. Omnivores are able to do this because they have a digestive system that can break down both plant and animal matter.
There are many different types of omnivores, including humans, bears, pigs, and raccoons. Humans are omnivores because we eat a variety of foods, including fruits, vegetables, grains, meat, and dairy products. Bears are omnivores because they eat plants, insects, fish, and small mammals. Pigs are omnivores because they eat fruits, vegetables, roots, and insects. Raccoons are omnivores because they eat insects, fruit, nuts, and small animals.
Omnivores play an important role in the ecosystem by helping to keep populations of plants and animals in balance. For example, bears help to control the population of insects and small mammals, which can damage crops and gardens. Pigs help to turn over soil and aerate it, which helps plants to grow. Raccoons help to control the population of insects and rodents, which can carry diseases.
The ability to be an omnivore gives animals a significant advantage in the wild. It allows them to adapt to changes in their environment and to find food sources that are not available to other types of animals. For example, if a bear's food source is limited, it can switch to eating insects or small mammals. This ability to adapt is essential for survival in the wild.
How can the word be used?

What do omnivores eat?
AQA Science Exam Question and Answer
Question:
Define what an omnivore is and provide examples of omnivores in the animal kingdom.
Answer:
An omnivore is an organism that has a diet that includes both plant matter and animal flesh. This dietary behaviour allows omnivores to obtain nutrients from a wider range of sources, giving them adaptability and flexibility in various environments.
Examples of omnivores in the animal kingdom are bears, humans, and pigs. Bears consume both plants, like berries and fruits, and animals, such as fish and small mammals. Humans have a diverse diet that consists of vegetables, fruits, grains, and meats. Pigs are opportunistic eaters, foraging for roots, insects, and occasionally small animals. These examples illustrate the diverse feeding strategies that omnivores employ to meet their nutritional requirements.
Omnivores have evolved to take advantage of available food sources, which can vary in different habitats and seasons. This adaptability provides them with an ecological advantage, as they can thrive in a wider range of environments compared to animals with more specialised diets.
