The correct answer is: All of the above.
Invasive plant species can pose a threat to Manipur’s native vegetation by outcompeting native plants, altering ecosystems, and reducing biodiversity.
Outcompeting native plants: Invasive plants can outcompete native plants for resources such as water, sunlight, and nutrients. This can lead to the decline or even extinction of native plant populations.
Altering ecosystems: Invasive plants can alter ecosystems by changing the composition of plant communities, the availability of food and shelter for animals, and the flow of water and nutrients. This can have a ripple effect on other organisms in the ecosystem.
Reducing biodiversity: Invasive plants can reduce biodiversity by displacing native plants and animals. This can lead to a loss of genetic diversity, which can make ecosystems less resilient to change.
Invasive plants are a major threat to Manipur’s native vegetation. It is important to take steps to prevent the introduction and spread of invasive plants, and to manage those that are already present.
