Gause's principle of competitive exclusion states that:

  • Option 1)

    More abundant species will exclude the less abundant species through competition.

  • Option 2)

    Competition for the same resources excludes species having different food preferences.

  • Option 3)

    No two species can occupy the same niche indefinitely for the same limiting resources.

  • Option 4)

    Larger organisms exclude smaller ones through competition.
