Final answer:
The relationship between Karner blue butterfly larvae and ants is an example of mutualism, where both species benefit from the interaction. Mutualism is one of three primary types of symbiotic relationships alongside commensalism and parasitism.
Step-by-step explanation:
Types of Symbiotic Relationships
The interaction described between ants and the Karner blue butterfly larvae is a classic example of mutualism, one of the three primary types of symbiotic relationships. In mutualism, both species benefit from their interaction. In the case of the Karner blue butterfly larvae and ants, the larvae secrete a carbohydrate-rich substance which is an important energy source for the ants. In return, the ants protect the larvae from predators, increasing their survival chances.
Another form of symbiotic relationship is commensalism, where one species benefits while the other is neither harmed nor helped. An example of this would be birds nesting in trees without affecting the tree's health. Lastly, there's parasitism, where one organism benefits at the expense of another, such as a helminth feeding off its host.
