It depends on the species of the animals involved, and the size of the pack and family in question.
I say the wolves win due to speed and sheer numbers. Its weird thinking about it but I picture Bears working poorly in a group. I would see Bears having more success by themselves or with just one partner. WOlves are pros at packs.
A pack of wolves
The Wovles family is the "pack" that they are in
A black bear can eat a lone wolf, but since wolves live in packs, the black bear would prefer not to. When it comes to carrion fights, black bears will attack wolves and sometimes drive them away.
Yes, Wolves rarely do kill Bears if the pack is here to help the pack leader by jumping and clamping it's jaws on the back or the butt and the muzzle of the bear & then the bear will be killed and eaten by the whole pack of wolves for them to feed, especially carcasses of bison, elk, horses, deer, or male bears.
i think it is a pack because they are related to wolves and a family of wolves is a pack
another pack of wolves
Some do, some don't. Wolves do, but bears don't.
They are called a pack.
No animal would eat a pack of wolves. There can be as many as 20 in a pack.
Polar bears are solitary creatures; normally the only group of polar bears is a mom and some cubs, a family group. However, when several polar bears do end up together, the collective nouns are an aurora of polar bears or a pack of polar bears. Although pack is one of the collective nouns given, I believe that it's a misnomer since a pack infers a group working together like a pack of dogs, wolves, or coyotes. But even when polar bears are together, they don't work together.
pack of wolves
A pack consists of a bunch of other wolves, some of them might be related, but others might just be other wolves who joined in with the pack and are not related in any way.
