';Why?'; Because it's their nature. They don't have much brain, but they have an instinct to pick up the dead ant and put it down next to another dead ant. This happens randomly until the dead ants are in a pile, sometimes called the ants' graveyard. A colony of ants usually has more than one graveyard. It gets the dead ants out of the way of the living.
