What is the impact of invasive species on native species' genetic diversity?

• Invasive species increase genetic diversity by introducing new traits

• Invasive species often outcompete native species, reducing their genetic diversity

• Invasive species have no effect on genetic diversity

• Invasive species help to conserve genetic diversity in ecosystems

How does overharvesting affect genetic diversity within a species?

• It has no effect on genetic diversity

• Overharvesting can lead to a loss of genetic variation, making species more vulnerable

• Overharvesting leads to increased genetic diversity

• Overharvesting only affects the population size, not genetic diversity

How does habitat destruction affect biodiversity?

• It increases species diversity by creating new habitats

• It can reduce genetic diversity by isolating populations

• It has no impact on biodiversity
