When two species occupy the same niche, they compete for all the resources they need. The superiority of one species over another forces others to adapt and endanger them. This is called conflict elimination.
No two species can have exactly the same niche. Otherwise, you will be in direct competition for resources. In this case, one species is better than the other. When a lost species fails to adapt, it leads to extinction.
