A lion could easily escape a bear, and a lion would not be easy for a bear to kill.
you would let them eat a bear because people are more important
NO. Polar bears live in a much different continent and biome than a lion or cheetah, so there's no way that a lion or a cheetah could eat, let alone see a polar bear.
It is unlikely that a lion would typically target a bear as prey due to the bear's size and strength. While lions have been known to scavenge from bear kills, direct confrontations between the two species are rare.
it could. if the bear is still young and small, a lion (usually a grown up) can eat it. if the bear is dead or injured, lion can eat it too. if the bear is a grown up and does not have any injuries, lion will have to fight it in order to eat.
a lion and a tiger eat bears i am 100% sure
Bear, coyote, wolf, mountain lion...
A larger predator like a pack of wolves or a big cat such as a tiger or a lion could potentially eat a bear.
If the two animals occupied the same continent, a lion would probably eat a koala (which is not a bear) when it moved between trees. However, lions do not eat koalas, for the simple reason that koalas are native to Australia alone, and there are no lions in Australia.
Bears are more widespread, but, lions are more dangerous since a bear can eat almost anything, but a lion will only eat meat. I am going to say a lion.
I don't know & I don't care
