Characterizes a situation in which two or more groups need each other and must depend on each other to accomplish a goal important to each group

Interdependence.

Interdependence is the mutual reliance between two or more groups. This concept differs from the reliance in a dependent relationship, where some members are dependent and some are not.

In an interdependent relationship, participants may be emotionally, economically, ecologically or morally reliant on and responsible to each other. An interdependent relationship can arise between two or more cooperative autonomous participants. Some people advocate freedom or independence as the ultimate good; others do the same with devotion to one's family, community, or society. Interdependence can be a common ground between these aspirations.
