Question

Cichlid species became extinct from

• A. Lake Victoria
• B. Lake Elizabeth
• C. Royal Lake
• D. Chilka Lake

Answer 1

The correct option is A Lake Victoria

Cichlid species became extinct from Lake Victoria because of invasion by the predatory fish Nile perch. The Nile perch was an alien species that was introduced into the lake to improve fishing. However, this resulted in the extinction of the native cichlid fish. Cichlids were detritivores and hence, their extinction caused deterioration of the lake.
