Answer 1

A mouse it a prey. producers are plants

Answer 2

For the most part, a mouse is prey. Yes, mice are omnivorous, but they typically only eat vegetation. Usually they are eaten by other organisms, like cats, snakes, and birds. They are not producers because they do not produce their own food. Producers are most often plants and other photosynthetic organisms.
