Apart from possibly us, nothing. they're top carnivore in their habitat.
Siberian tigers have been known to take down Russian brown bears but somethimes its the other way around. No other animal kills and eats these bears

a hunter hunts brown bears and sometime eats them, ok losers bye for now!
When a brown bear eats a salmon it does not acquire all the energy contained in the body of the fish. This is because the bear's body is not efficient enough to obtain all of the energy from what eat eats. When the cells covert the protein of the fish into energy, it looses most of the useful energy in the process (the second law of thermodynamics proves this).
None, No polar bear eats pizza
A bear eats a coyote
Here's how it would work: Tiger or bear eats bat. Tiger or bear eats monkey. This leaves the bear and tiger to duke it out. So, what happens here really depends on the species of the tiger and the bear. Siberian versus black bear, chances are the Siberian will win. Bengal versus black bear, could be a draw or the black bear wins because tigers don't like going after animals that can fight back. Bengal versus grizzly or brown bear, high chance that grizzly or brown bear wins. Siberian versus grizzly or brown bear though, could be a draw, could end up that Siberian wins because brown bears actually make up 6% of the Siberian's diet.
A polar bear
Brown Bears and Seagulls don't have any kind of relationship what so ever. But the seagull does benifit from the Brown Bear because when the bear eats its prey, it leaves the remains left for other scavengers to eat it. Take a fish for example, when the Brown Bear is done with its meal, it leaves what is left for the seagull to eat, like fish. This is an example of Commensalism because one benefits from the other without being harmed.
