Which of the following is not a possible consequence of the introduction of invasive species?
a. changes to the existing gene pool
b. changes to an area s diversity
c. fragmentation, destruction, or alteration of habitats
d. no consequences

The correct answer is option d. No consequences.

The invasive species are those species, which are not native to a particular ecosystem. There native ecosystem is somewhere else than the region, in which they are present.

The introduction of the invasive species generally causes the disturbance to the ecosystem, as they exploit various resources present in the ecosystem and causes the suffering of the native species by increased competition and lack of vital components. Hence, the invasive species can easily change the diversity of the area and cause the changes in the gene pool. The species also affect the habitat and cause it destruction or alteration. So, they cause a lot of consequences to the ecosystem.
