No two species can occupy the same niche in the same habitat at the same time because?

This is the Theory of Competitive Exclusion. The limited resources in an ecosystem must be partitioned between two species in some way otherwise they would be competing "head to head" for all their life's needs, and this would be a serious waste of their energy Two species can occupy the same niche. Interspecific competition is responsible for the resulting relative abundances (# of each organism) in the community.

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.
