Humans are generally classified as omnivores; they eat both animals and plants.
What are Omnivores?
An omnivore is usually defined as an animal whose species normally derives its energy and nutrients from a diet consisting of a variety of food sources that could include plants, animals, algae, fungi, and bacteria. Some omnivores are known to hunt and eat their food, like carnivores who consume herbivores and other omnivores. While others are scavengers and eat dead matter. Many do eat eggs of other animals.
Many omnivores evolved to this state after many years and are known as opportunistic feeders since they rely on both vegetation and animal protein to remain healthy. Hence it becomes comparatively easier for an omnivore to get food since they have a lot more choices than either carnivores or herbivores. The diet of most omnivorous animals changes according to the season and availability. This is because if one food item becomes scarce or doesn’t grow during winter they move on to the next.
Besides humans, there are many different species that live on an omnivorous diet. Some common mammalian omnivores include raccoons which are one of the best examples of an opportunistic eater, raccoons are not very picky and eat anything from mice, frogs, fish, insects, fruits, vegetables to even waste, also there are opossums, skunks, pigs, rats, badgers and most bear species. The jerboa is a type of rodent found in the dessert that eats plant seeds and insects. Roadrunner sometimes eats fruits and other times small rodents. The catfish, damselfish, and parrotfish are omnivores that call the water their home and also eat phytoplankton and other smaller fish. The grizzly bear happens to be an omnivore that resides in the arctic. There are also several omnivorous birds, including chickens, crows, and robins. Some reptiles, such as lizards and turtles are also omnivorous.
