Ans:
a. Character displacement
Explanation: Character displacement is the phenomenon where two species changes their form and resource uses when they are live together in the same environment i. e. divergence in resource-exploiting traits. Competitive exclusion states that complete competitor cannot coexist i. e. one competing species will eliminate or exclude the other. Batesian mimicry is a type of mimicry where a vulnerable organism gains a selective advantage by looking like a dangerous or distasteful organism. Mutualism is the symbiotic association between two different species where both are benefited.

27. Two species of yeast persist indefinitely when each species is grown on agar in separate petri dishes in the lab. However, when the species are grown together on agar in the same petri dish, only a single species remains after a few days. What is the most likely explanation for the elimination of one of the species? a) Competition between the two yeast species resulted in a change in the way the two species used the limited resource (agar)....
