Answer:

Explanation:
Omnivores is one of the classification of animals based on their feeding pattern characterized by their ability to feed on both other animals (flesh) and plant materials. They can behave like carnivores and also like herbivores in terms of what they feed on. Due to this property they possess, they can be found in any trophic level except the first trophic level.
Omnivores can never be found in the first trophic level because they are also consumers, and that role of beginning energy flow in a food chain by obtaining energy from sunlight belongs to autotrophs called PRIMARY PRODUCERS. Omnivores can now because of their ability to feed on plants and animals, exist from the second trophic level upwards.
