Step 1: Understanding the Concept:
Competition occurs when two species require the same resource (like food or space) that is in short supply.
Step 2: Detailed Explanation:
A well-known example of interspecific competition is between the Abingdon tortoise and goats on the Galapagos Islands.
When goats were introduced to the islands, they competed with the tortoises for the same vegetation.
Because goats had a much higher browsing efficiency, they consumed the vegetation much faster than the tortoises.
As a result, the Abingdon tortoise became extinct within a decade of the goats' introduction.
Step 3: Final Answer:
The extinction of Abingdon tortoises due to the introduction of goats is a prime example of interspecific competition.
