The carrying capacity of Paramecium aurelia living alone (without p. caudatum) in gause's lab flask with nutrients is about 550. This is a true statement.
Paramecium populations reached carrying capacity on day 12. This was because that day was the largest amount of paramecium ever recorded.
Competition is a type of population interaction in which the fitness of one species is significantly reduced in the presence of another species. This occurs when multiple species compete for the same resource, limiting it and adversely affecting both interacting species.
Both Paramecium aurelia and Paramecium share the same niche because he was grown together in one flask using bacteria as a food source.
From the above figure, we can see that Paramecium aurelia grew well in the mix, but Paramecium caudatum did not. Therefore, Paramecium caudatum (less competitive) was eliminated because he could not compete with Paramecium aurelia (more competitive) for the same limited food source.
This is because two closely related species competing for the same resource cannot coexist indefinitely, and when resources are limited, the competitively inferior species will eventually be eliminated. An example of Gause's principle of competitive exclusion.
