In which type of interaction do both organisms have significant advantages from their relationship?

The correct answer is synergism, which refers to a type of interaction where both organisms involved gain significant benefits from their relationship. In a synergistic relationship, the combined effect of the two organisms working together leads to a more favorable outcome than if they were to operate independently.

For instance, certain types of bacteria cooperate to break down complex organic materials more efficiently than one species could alone, benefiting both organisms in their nutritional needs. This symbiotic partnership showcases how they can enhance each other's capabilities and overall success within their environment.

Antagonism, on the other hand, typically involves one organism benefiting at the expense of another, resulting in a negative outcome for one party. Parasitism also aligns more with a one-sided benefit where one organism gains while harming the other. Commensalism involves one organism benefiting while the other is neither helped nor harmed, thus not providing the mutual advantages seen in synergism.
