• C. South America

Answer 1

The correct option is B East Africa


Introduction to alien species invasion

Intentional or unintentional introduction of alien species into a habitat may result in competition between the indigenous species and the alien species if they require the same resources for survival. Often the superior alien species becomes invasive and causes the population of indigenous species to decline, ultimately leading to extinction of the species.

Nile perch

Lake Victoria of east Africa possessed a surprisingly diverse community of cichlids. In the 1950s, the fish species Nile perch was introduced to Lake Victoria to boost the fishing industry.

This caused huge economic benefit, but also drove nearly 200 species of native cichlids to extinction as the cichlids were their prey.

Final answer

(d.) East Africa
