Vedclass · Answer

(B) The 'Rivet Popper Hypothesis' was proposed by the ecologist $Paul Ehrlich$. This hypothesis uses an analogy of an airplane to explain the importance of species diversity in an ecosystem. In this analogy,the ecosystem is compared to an airplane,and the species are compared to the rivets holding the parts together. If passengers start popping rivets (extinction of species),the flight safety is initially unaffected,but as more rivets are removed,the plane becomes dangerously weak and eventually crashes,representing the collapse of the ecosystem.
