Question

Gause's principle of competitive exclusion states that
A)More abundant species will exclude the less abundant species through competition.
B)Competition for the same resources excludes species having different food preferences.
C)No two species can occupy the same niche indefinitely for the same limiting resources.
D)Larger organisms exclude smaller ones through competition.

Answer 1

In Georgy Gause experiment, Paramecium aurelia and Paramecium caudatum thrive properly independently, but P. aurelia outcompetes P. caudatum as they fight for the same resources.

Complete answer:
Based on laboratory competitiveness research the use of two kinds of Paramecium species, P. aurelia and P. caudatum, Georgy Gause proposed the law of competitive exclusion. The specifications have been to supply clean water every day and provide a steady supply of food. While P. caudatum originally dominated, by way of exploitative resource competition, but P. aurelia survived and sooner or later drove P. caudatum extinct. However, by means of varying the environmental parameters (food, water), Gause was once able to assist P. caudatum live. Therefore, Gause's rule is solely real if the ecological variables are stable.

Now, let us locate the solution from the options-
The idea of competitive exclusion also referred to as the Competitive Exclusion Law of Gause or just the Law of Gause, states that two animals that compete over the very same assets are unable to coexist stably.
In the long term or an evolutionary exchange of the weaker competitor into a precise ecological niche, one of the two opponents will nevertheless have an ever so small benefit over the other that leads to the disappearance of the 2nd competitor. As a result,
in environments where they all coexist, competing associated species additionally establish distinguishing characteristics.

Hence, the correct answer is option (C)

Note: Georgii Gause is classically attributed to the theory of aggressive exclusion, though he in no way really proposed it. In Darwin's theory of herbal selection, the idea is already present. The state of the concept has oscillated during its records between a priori ('two coexisting species need to have awesome niches') and experimental actuality ('we word that coexisting species have distinct niches')
