Biological interactions range from mutualism, beneficial to both partners, to competition, harmful to both partners. Interactions can be direct when physical contact is established or indirect, through intermediaries such as shared resources, territories, ecological services, metabolic waste, toxins or growth inhibitors.
In game theory, a win–win game or win–win [1] scenario is a situation that produces a mutually beneficial outcome for two or more parties. [2] It is also called a positive-sum game as it is the opposite of a zero-sum game.
