The foods an animal eats are its remains?

This question is quite confuiaing but I'll try my best. If an animal is eating one of its one species, then this is known as cannibalism. Some animals however, feed on the carcass of their prey which has been left behind by anither animal which has evidently been fed well and eaten as much as they could. I hope this helped.

Well if like a rabbit ran in front of your moms or dads car and they acidently hit and a cople hours later a bird has aten it and ate everything exept the bones and some of the fur the bones and the fur whould be the remains.
