Text Solution

Verified by Experts
The correct answer is:
D

The Rivet Popper Hypothesis (proposed by Paul Ehrlich) compares the stability of an ecosystem to the safety of an airplane, where each rivet represents a species. Removing rivets (species loss) weakens the airplane (ecosystem), and beyond a point, the system collapses.

Rivets – Species → Comparable (rivets symbolize species).

Airplane – Ecosystem → Comparable (airplane symbolizes ecosystem).

Safety of flight – Stability of ecosystem
