Which of the following is a consequence of invasive species in ecosystems?

Invasive species are organisms that are introduced to an ecosystem where they are not native, often leading to significant consequences for the existing local biodiversity and ecological balance. The correct response highlights that these species typically disrupt local ecosystems.

Invasive species can outcompete native species for resources such as food, space, and light, often leading to declines in native populations. This disruption can also alter the food web dynamics, affect soil chemistry, and impact interactions among species, which may lead to unforeseen ecological consequences. For example, they can introduce diseases to which native species have no resistance or change the habitat structure that native species depend on.

This contrasting dynamic demonstrates the importance of preserving native species and habitats, as invasive species tend to pose a threat with their ability to spread rapidly, often leading to reduced biodiversity and altered ecosystem functions. The other options imply positive outcomes, which generally do not occur with invasives, thus reinforcing the disruptive impact they have on local ecosystems.
