d. Fire ants spread by winged members and by hitching rides so a single colony can cause infestation.
Explanation:
An invasive fire ant colony can be very disastrous to the population of organisms in a locality. They cause massive competition with the native species thereby infesting them and destroying the native population.
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.
