What is the competitive exclusion principle?

Answer:
The competitive exclusion principle states that no two species can coexist if they occupy the same niche and compete for the same resources.

There are two possible outcomes of the competition:
  • One species is less capable and becomes extinct.
  • One species undergoes an evolutionary or behavioral shift towards a different ecological niche.
