Greetings!
A producer lies at the bottom of the food chain, while consumers gather towards the top. Consumers are the only living things on the food chain that can be considered herbivores, carnivores, or omnivores, because they do not make their own food like producers do.
Herbivore                Omnivore              Carnivore
Deer                    Bear                   Snake
Horse                   Human                 Cat
Mouse                   Fish                   Frog
Rabbit
And of course here are the producers:
Algae
Grass
Pine tree
Palm tree
Tomato plant
Wheat
Hope this helps! Have a nice day :)
