Name two animals that are omnivores. give an example of a plant and an animal that each one might eat.

Two animals that are omnivores are: 
Bears and Badgers
Bears eat clover and other plants, and they eat salmon and other animals.
Badgers eat plants such as different fruits like pears and plums, and Badgers eat earthworms, insects, amphibians (such as frogs) reptiles and birds.

Humans are omnivores. We eat both meat and plants. We eat green beans, peas, carrots, and corn. we also eat chicken, fish, pork, hamburger, salmon, and shrimp . Dogs are omnivores. In some dog food there is vegetables and there is also meat. For example, the meats would be chicken, pork, and salmon. The plants would be green beans, peas, and corn. Plants would basically be considered "vegetables." 
Now you try and think of some more!
Hope this helps you!
