Step-by-step solution
According to the competitive exclusion principle, when two species compete for the same limited resources, the competitively superior species will eventually eliminate the other.
The Abingdon tortoise in the Galapagos Islands became extinct within a decade after goats were introduced on the island. This occurred because the goats had a greater browsing efficiency compared to the tortoises, leading to a lack of food resources for the tortoises.
Thus, Assertion A is correct, and Reason R is also correct and provides the correct explanation for Assertion A.
Answer: Both and are correct and is the correct explanation of
