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.
The competitive exclusion principle states that two species cannot occupy exactly the same niche in a habitat. In other words, different species cannot coexist within a community if they compete for the same resource.

Sociologist who studied both poor and affluent Chicago schools and found that administrators expected less of children was Howard Becker.
American sociologist Howard S. Becker, whose full name is Howard Saul Becker, was born in Chicago, Illinois, on April 18, 1928. He is renowned for his research on deviance, art, and occupations.
One of the pioneering works on labelling theory and its use in deviance research is Becker's 1963 book Outsiders. Becker investigated the idea that deviance is merely a social fabrication designed to instil fear and penalise particular groups in the society. Becker writes that deviation is "not a trait of a terrible person but the result of someone classifying someone's conduct as wrong" in the book.
