How does the introduction of exotic species affect the invaded land?
It causes harm to the native species
It increases species diversity
It becomes stable and does not spread rapidly
It starts spreading rapidly
Solution
When certain exotic species are introduced into a geographical area, they become invasive and start spreading fast. This happens because the invaded land does not have its natural predators. The exotic species can cause havoc to the ecosystem by spreading rapidly into millions of hectares of land, as demonstrated by the prickly pear cactus introduced into Australia in the early 1920’s.
