What is the term for the disappearance of a species from Earth?

• A. Migration
• B. Extirpation
• C. Extinction
• D. Endangerment

Answer: (C)

Extinction means a species no longer exists anywhere on Earth. It’s the final end of that species’ global presence, so there are no living members left to reproduce and continue the lineage. This is why it’s the best term for the disappearance of a species from Earth. Migration would just be moving individuals to a new area, not disappearing entirely. Extirpation describes a local disappearance in a specific area, but the species still lives elsewhere. Endangerment means the species is at high risk of extinction, but it still has surviving individuals.
