Question

In “Rivet popper hypothesis” Paul Ehrlich, the rivets on the wings represents _ _ _ _ _ _ _ _ _ _ _ in the ecosystem
(a)key species
(b)Exotic species
(c)Extinct species
(d)Invasive species

Answer 1

Hint: The rivet popper hypothesis focuses on the ecosystem and the consequences of loss of a species from the ecosystem and how it may affect the same. Such species, when lost, ecosystem gets affected the most.

Complete answer:
An ecosystem is based on the coexistence of certain species and communities along with the environment. Through the study of ecosystems, one can also infer the interactions between species or a community with its immediate environment and habitat. If certain species that are valuable to the environment and ecosystem, start to disappear, it may cause huge harm to the same. The rivet popper hypothesis proposed by Paul Ehrlich signifies the consequences of the loss that an ecosystem may face from the disappearance of such species. In this hypothesis, Paul Ehrlich compares the key species with the rivets of an airplane and he proposed that if the rivets are taken out gradually then ultimately the plane would also crash too. Hypothesis signified that if key species are taken out of an ecosystem, their non-existence would eventually harm the ecosystem not in the immediate future but in the long run.

Additional Information: -Species which have had an impact on the climatic conditions of a particular area, if such species get destroyed then it will rapidly change the climatic conditions in that particular area and the total ecosystem will be affected.
-Initially, it is seen that the extinction of a key species may or may not affect the immediate environment that they belong to but in the long run, it may affect the functioning of the ecosystem.
-In the rivet popper hypothesis the wings are the most important part of the airplane that keeps the airplane in the air, so PaulEhlrich compared to the key species with the most important part of an airplane without which the airplane would have had no function.
So, the correct option is. “key species”.

Note: -You must note that in the ecosystem there is the presence of many species but every ecosystem has a key species which when lost affects the ecosystem the most.
-You must note that the key species play the most important role in the ecosystem they live in.
