If you mean what deer eat then they eat grasses, branches. But if you mean what preys on deer then it would be wolves, mainly if the deer were atacked by a large pack, otherwise the deer that don't live were wolves are it would depend on what carnivors could bring it down in its area this is not true get that from me aka little mustard head but tooth self.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
