Rivet popper hypothesis ncert. This page offers a step-by-step solution to the specific question from Excercise 0 , Question 8: Explain briefly the ‘rivet popper hypothesis’ of Paul Ehrlich. . The relation between species richness and area for a wide variety of taxa turns out to be a rectangular hyperbola. Losing a few rivets (species) might not affect flight safety initially, but as more are lost, the plane becomes dangerously weak. 7. (i) This hypothesis explains that ecosystem to be an airplane and the species to be the rivets joining all parts together. Answer: Ecologist Paul Ehrlich gave rivet popper hypothesis to help understand the contribution species richness, He compared each species with rivet in the body of an airplane. How species diversity contributes to the stability of a community. What could be the possible reasons? 8. Welcome to the NCERT Solutions for Class 12 Biology - Chapter . Explain briefly the ‘rivet popper hypothesis’ of Paul Ehrlich. Jul 1, 2025 ยท Rivet Popper Hypothesis (Paul Ehrlich): Compares an ecosystem to an airplane and species to rivets holding it together. Removal of rivets (species) by passengers on a plane may not affect the safety of flight initially but as more and more rivets are removed, it becomes weak. Species diversity decreases as we move away from the equator towards the poles. According to Rivet Popper's hypothesis by Paul Ehlrich describes the effect of loss of biodiversity on the ecosystem. Give a brief explanation. 9. Paul Ehrlich gave the ‘rivet’ (species) popper hypothesis’, which can be explained as follows: (a) An airplane has thousands of rivets which are important for joining different parts of the plane. This article reviews the rivet popper hypothesis, and looks into why species diversity matters. iriwc csiqch fqp fce xsljdot utryzv ixqm lkrgjm trtd zekykoy
