Here's why:
* Primary consumers eat producers (plants).
* Secondary consumers eat primary consumers (herbivores).
Omnivores eat both plants and animals, making them capable of fulfilling both roles in the food chain.
Examples of omnivores:
* Humans: We eat fruits, vegetables, meat, and dairy.
* Bears: They eat berries, fish, and other animals.
* Raccoons: They scavenge and eat a wide variety of food, including fruits, insects, and small animals.
* Pigs: They are known to eat both plants and animal scraps.
