Read the following given examples :

(i)   Plant – pollinator mutualism

(ii)  Lichen

(iii)  African catfish during aquaculture

(iv) Nile perch and cichlid fish.

Which out of these options correctly gives the example of ‘co-extinction’ as a cause of biodiversity loss?

Those organisms which live in very close association have higher chances of undergoing co-extinction. Mutualism (lichens, plant-pollinator interaction), parasitism are two interactions which may exhibit co-extinction.

African cat fish and Nile perch are examples for invasive, alien species.
