The additional characteristic of the Kudzu vine that determined it was an invasive species is that it grows rapidly, robbing other plants of sunlight.
Invasive species are a huge threat to ecosystems because they can do intense damage, so much so that ecosystems may not be able to recover.
An organism is considered an invasive species if it does harm and is introduced to the ecosystem.
Decomposers provide the ecosystem service of nutrient cycling.
Ecological resistance is the ability of an ecosystem to endure in changing conditions.

b
Invasive species provide no added benefit or diversity to the ecosystem.
c
Invasive species are impossible to control once they are introduced and spread rapidly.
