Is the ermine a consumer

small mammals

such as a rabbit

Yeah it does ^^^ But a more detailed answer is:

They do not eat plants- they are carnivores. Their main diet is rabbits and rodents, but they can eat other mammals, even some bigger than themselves. Their diet can also include: Birds, eggs, frogs, fish, small hares and insects. When they need to, they can eat berries.

Please understand that they can only eat the above IF it is availible.

Hope this helps,
