Which scientist proposed 'Rivet popper hypothesis' related to biodiversity and Ecosystems?

Explanation

What if we lose a few species ? Will it affect man.s life ? Paul Ehrlich experiments Rivet popper, hypothesis, taking an aeroplane as a ecosystem, explains hoow removal of one by one .rivets. (secies of an ecosystem) of various parts can slowly damage the plane (ecosystem) shows how important a .species. is in the overall functioning of an ecosystem. Removing a rivet from a seat or some other relatively minor important parts may not damage the plane, but removal of a rivet from a part supporting the wing can result in a crash. Likewise, removal of a .critical species. may affect the entire community and thus the entire ecosystem.
