I guess they would if they could! Emus are native to Australia only and Australia has no lions. Therefore, in the current status quo - no, lions do not eat emus. It should be noted that emus possess a unique defence capability, which would aid them if they were in the position of having to outrun a lion. When running at top speed, the physiological structure of their feet enables them to make sudden 180-degree turns which not even a small cat can do: by the time a bigger cat such as a lion slowed enough to make the turn, the emu would be 50-60 metres ahead in the opposite direction.
Lions do not eat bears as there is nowhere where they live in the same habitat and they are both top carnivores. Lions would probably eat emus if they could but emus live in Australia where there are no lions.

Otters are also prey to brown bears, sea lions, and bald eagles.
In florida, Alligators, crocodiles, pythons, mountain lions, and black bears are predators.
Brown bears and lions do not live in the same part of the world, so the question does not really come up. Both are predators, and predators do not usually hunt predators- they hunt prey. Prey do not have huge claws and teeth to defend themselves. Predators do. A brown bear would prefer to go eat a salmon.
