Answer: C. A species is brought to a new environment where it has no predators.
Step-by-step explanation:
According to the Green Invaders article, invasive species are plant species that people brought with them when they moved to the United States because they wanted to make the vegetation more aesthetically pleasing.
The article mentioned how this could be bad for the ecosystem however because most insects are plant specific which means that they only feed on certain plants and without those plants, they could die off.
The insects are the predators for plants therefore and if they are unable to eat these new invasive plant species then that means that these plant species are now in an environment where they have no predators.
