Q.
In "rivet-popper hypothesis", the wing rivets are compared with
NTA AbhyasNTA Abhyas 2022
Solution:
The rivet popper's hypothesis was proposed by Paul Ehrlich. In an airplane (ecosystem) all parts are joined with rivets (species). If every passenger traveling in it starts popping a rivet to take home (causing a species to become extinct), the plane may become dangerously weak over time. Loss of rivets from wings (key species that drive the major ecosystem function) is obviously a more serious threat to flight safety.
