Which of the following represents the correct order of global biodiversity loss for the listed groups, from highest to lowest percentage of threatened species?
- A.Amphibians > Mammals > Gymnosperms > Birds
- B.Amphibians > Gymnosperms > Mammals > Birds
- C.Gymnosperms > Amphibians > Mammals > Birds
- D.Mammals > Amphibians > Birds > Gymnosperms
Show correct answer & step-by-step solution
Correct answer: B — Amphibians > Gymnosperms > Mammals > Birds
Solution
- Reviewing IUCN Red List data for global species extinction risk.
- Amphibians are the most threatened group at approximately 32 percent.
- Gymnosperms follow at approximately 31 percent.
- Mammals are at approximately 23 percent and birds at 12 percent.
- Hence the answer is (B).
