Which term describes the relationship between fire ant and native ant populations? 

A)  mutualism

D)  intraspecific competition

Fire ants are invasive species, and they often outcompete native ant populations for resources such as food and habitat. This type of interaction between two different species is called interspecific competition. Mutualism refers to a relationship where both species involved benefit from the interaction, commensalism refers to a relationship where one species benefits while the other is unaffected, and intraspecific competition refers to competition between individuals of the same species.
