Answer:
Lion have strong teeth and jaws and are able to tear the meat with their sharp teeth.
There is a pecking order in a pride, and the male lion will normally be the first to eat. There after, the lionesses and the cubs may have their turn. The male will eat first even if the hunt was performed by the lionesses.

I agree with the above answer, but the male lion usually eats the first because otherwise, nothing would be left by lionesses and cubs for him. However, the male lion always keep partially the prey to be eaten by lionesses and cubs. Lion has more nobility than quite a lot of people believe.
