1.	Explain the Rivet Popper hypothesis.
Answer» According to Rivet Popper hypothesis by Paul Ehlrich describes the effect of loss of biodiversity on ecosystem. Removal of rivets (species) by passengers on a plane may not affect safety of flight initially but as more and more rivets are removed, it becomes weak. Removal of rivets of a critical part like wing (species performing major ecosystem functions) will pose a very serious immediate threat to the safety of the flight. In an ecosystem various species act as rivets and role of each species is important and well defined.
