Correct Answer: Rivet Popper hypothesis


Solution : The correct answer is the Rivet Popper hypothesis.

Paul Ehrlich put forth the Rivet Popper Hypothesis. According to the hypothesis, species richness is crucial to the ecosystem's ability to remain intact. The Rivet Hypothesis compares the increasingly critical impact that the extinction of each species will have on an ecosystem's ability to function using the analogy of rivets in an aeroplane wing (Lawton, 1994).
