Step-by-step solution
(A) Habitat loss and fragmentation is exemplified by the clearing of the Amazon rain forest for cultivating soya beans or for conversion to grass lands. (B) Over-exploitation by humans led to the extinction of the passenger pigeon and Steller's sea cow. (C) Alien species invasions are represented by the introduction of the Nile perch into Lake Victoria, which caused the extinction of native cichlid fish. (D) Co-extinctions occur in obligate associations, such as plant-pollinator mutualism, where the extinction of o
