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.

Their reactions
are best explained in terms of "Classical Conditioning".
<span>Classical conditioning is a learning procedure that happens
when two stimuli are more than once matched: a reaction which is at first
inspired by the second boost is in the end evoked by the primary stimuli alone.
It is important to know that classical conditioning includes automatic or
reflexive responses, and not intentional conduct.</span>
