explain rivet popper hypothesis? what is key species in it? (5MARKS)

Rivet-Popper hypothesis was given by famous ecologist Paul Ehrlich. In this hypotheisis -Paul has thrown light on the importance of various components(like different species) of ecosystem  by comparing ecosystem with an aero plane and its components with the airplane rivets. Rivets are nothing but the various bolts which complete the design of plane & help it in flying. If passengers , travelling in the plane found those rivets useful for any of their personnel purpose and take away them then it will result in the unsafe flight and  can lead to plane crash. In the same way,  different components of ecosystem play an important role in maintaining its balance. So, humans should not disturb/use them  for their own benefits as it it ultimately result in the loss of  ecological balance.
