Rainbow [258]

Answer:

d.  Fire ants spread by winged members and by hitching rides so a single colony can cause infestation.

Fire ants spread by winged members which makes a single colony to cause severe damage to the native specie. Often times, as they become endemic, they manifest as the dominant specie in a particular location.
