Detailed explanation-1: -Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats. This can result in huge economic impacts and fundamental disruptions of coastal and Great Lakes ecosystems.
Detailed explanation-2: -Invasive alien species have devastating impacts on native biota, causing decline or even extinctions of native species, and negatively affecting ecosystems. Invasive alien species are animals, plants, fungi and microorganisms entered and established in the environment from outside of their natural habitat.
Detailed explanation-3: -When a new and aggressive species is introduced into an ecosystem, it may not have any natural predators or controls. It can breed and spread quickly, taking over an area. Native wildlife may not have evolved defenses against the invader, or they may not be able to compete with a species that has no predators.
Detailed explanation-4: -Introduced species often become invasive because other organisms that share their native environment and have evolved with them to achieve ecological balance usually aren’t present in the new habitat, so the introduced species is no longer subject to a natural check that evolved in response to its presence.
