• D. A - Lake Victoria, B - 200, C - cichlids

Answer 1

The correct option is D A - Lake Victoria, B - 200, C - cichlids

Alien species (non-native species), introduced unintentionally or deliberately into any habitat can often turn invasive and lead to the decline or extinction of native or indigenous species.

The introduction of the Nile Perch (large food and game fish) into Lake Victoria of east Africa was done to boost the fishing industry but this alien species became invasive and started preying on the native cichlids (fishes) of the lake.

Thus, although the introduction led to an economic boom, it led to the extinction of more than 200 species of native cichlids.
