* Producers: Plants, which make their own food through photosynthesis.
* Primary Consumers: Herbivores and omnivores that eat producers (plants) like squirrels, rabbits, deer, etc.
* Secondary Consumers: Carnivores and omnivores that eat primary consumers, like snakes, foxes, owls, etc.
* Tertiary Consumers: Predators that eat secondary consumers, like hawks, eagles, etc.
Squirrels are eaten by a variety of predators like hawks, owls, snakes, foxes, and even larger animals like bobcats and bears. So, they play an important role in the food chain by both consuming producers and being consumed by predators.
