Step-by-step solution
The 'Evil Quartet' describes the four major causes of biodiversity loss. (A) Extinction of passenger pigeon is due to overexploitation by humans. (B) Introduction of Nile perch into Lake Victoria led to the extinction of native cichlid fish, which is an example of alien species invasion. (C) Clearing of the Amazon rain forest for cultivating soya beans or for conversion to grasslands is a classic example of habitat loss and fragmentation. (D) Breakdown of plant-pollinator mutualism leads to the extinction of one sp
