What the Bengal tiger eat?

Answer 1

Nothig but humans. Hunting them.
Adult Bengal Tigers have no natural predators (Apart from man). No other animal in the forest is strong enough to kill a full grown adult Tiger.

Humans, armed with their guns and traps are much more powerful than a tiger and can easily kill them. That is why, man is the tigers biggest enemy

Tiger cubs may be killed by leopards, hyenas, or dhole(wild dogs).

Adults are sometimes killed by large dhole packs, although at a tremendous loss of numbers of the dogs. These conflicts however, are very rare, as tigers often drive dholes from their kills.

Answer 2

This big cat is a carnivore. It only eats meat. Anything it can catch. A deer or a bird, any animal is game to this biggest cat.
