how are the feeding relationships of the mice diffrent from the feeding relationships of the other organisms?

Answer 1

I am not quite sure what you mean but I do know they usually eat the similiar, if not the same, things. Although, only mice tend to eat cheese. I also know the rats are more prone to eating from garbage. Guinea pigs and hamsters tend to eat more of the pet food or grains and such.

Answer 2

Other organisms don't necessarily eat cheese.
