Question

Why are invasive species such a huge threat to ecosystems?(1 point)

Invasive species are impossible to control once they are introduced and spread rapidly.

Invasive species provide no added benefit or diversity to the ecosystem.

Invasive species can replace native species, forcing their migration out of the area.

Invasive species can do intense damage, so much so that ecosystems may not be able to recover.

Answer 1

Invasive species can do intense damage, so much so that ecosystems may not be able to recover.

They outcompete or prey on native species, introduce diseases, and alter habitats and ecosystem processes (nutrient cycles, fire regimes, etc.), sometimes causing irreversible change.
