Consider the following matched-(1) Birds facing extinction – 12...
As per November 2004 Global species assessment by world conservation union(IUCN) found that 12% of all bird species are threatened with extinction.
Nile perch-alien species invasion:It means fish is not a natural part of ecology of Lake Victoria.The lake cichlids have no defense against the unfamiliar predator.
Passenger pigeon-over exploitation: Primary threats to passenger pigeon were over exploitation the lack of protective regulations aided by habitat destruction and probably density dependent population effects the doomed species to extinction once population shrank.
So all the three sentences are correct.

Consider the following matched-(1) Birds facing extinction – 12...
Explanation:
Birds facing extinction – 12 percent
- This match is correct as 12 percent of bird species are facing extinction due to various factors such as habitat loss, climate change, pollution, and hunting.
Nile perch – alien species invasion
- This match is correct as the Nile perch is an alien species that was introduced to Lake Victoria in Africa and has caused significant ecological harm by outcompeting native species.
Passenger pigeon – overexploitation
- This match is correct as the passenger pigeon was once the most abundant bird in North America but was driven to extinction due to overexploitation by humans for food and feathers.
Therefore, all three matches are correct. This understanding of the causes of extinction and endangerment of bird species is essential for conservation efforts to protect and preserve biodiversity.
