Organisms have niches so that they can survive. If every other organism is trying to do the same thing, there would be lots of competition and this makes it difficult for the organism to survive. If you do something that no one else does, there's less competition and therefore more food for you. So organisms that find a unique niche, procreate more and survive better.
