What is considered as the rivet in the ‘Rivet popper hypothesis’? Correct Answer Species

Paul Ehrlich, a Stanford ecologist gave the ‘Rivet popper hypothesis’. In this hypothesis, he considered species as a rivet. This hypothesis provides a perspective on what might happen if a few species of the planet are extinct.
