There are a few examples of possible symbiotic relationships for black bears. It could be said that they have one with humans, as they commonly eat trash which is left out by humans.

No, humans belong to the class Mammalia, while bears belong to the class Mammalia as well. Both humans and bears are mammals, but they belong to different orders (Primates for humans and Carnivora for bears).
No grizzly bears only attack humans if they think that you are going to cause harm to them...... Or grizzly bears attack humans if they get frightened by them..... But they rather have honey than humans
