In the context of the rivet popper hypothesis, what does the removal of a key species represent?
- A.Loss of a minor rivet causing immediate ecosystem collapse
- B.Loss of a critical rivet leading to a significant decline in ecosystem function
- C.Loss of a rivet that has no impact on the structural integrity of the airplane
- D.Increase in the number of rivets to compensate for the loss
Show correct answer & step-by-step solution
Correct answer: B — Loss of a critical rivet leading to a significant decline in ecosystem function
Solution
- Paul Ehrlich proposed the rivet popper hypothesis to explain the importance of biodiversity.
- Species are compared to rivets holding an airplane together.
- Removing minor rivets may have little effect, but removing a key species (a critical rivet) compromises the structural integrity of the ecosystem.
- Hence the answer is (B).
