The Competitive Exclusion Principle

Q. Gause's principle of competitive exclusion states that:

1. More abundant species will exclude the less abundant species through competition
2. Competition for the same resources excludes species having different food preferences
3. No two species can occupy the same niche indefinitely for the same limiting resources
4. Larger organisms exclude smaller ones through competition

Q. According to Gause, if two species are occupying same ecological niche and competing for common resources then

1. both species will eliminate each other
2. inferior type will eliminate the superior type of species
3. superior species will exclude the inferior type of species
4. both species will remain unaffected

Q. Read the following statements (A - D) related to competition and select the correct option stating true (T) and false (F).

A. In a habitat with limited resources, the competitively superior organism will eliminate the inferior organism.
B. The Abingdon tortoise in Galapagos island became extinct due to the greater grazing efficiency of goats.
C. In interference competition, the competition between organisms is indirect.
D. In intraspecific competition, the competing organisms belong to different species.

1. A - T, B - F, C - T and D - F
2. A - T, B - T, C - F and D - F
3. A - F, B - F, C - T and D - T
4. A - F, B - T, C - F and D - T
