Mutually beneficial interactions, in contrast, may become so interdependent that each organism requires the other for survival. Although the species involved in competitive, predatory, and mutually beneficial interactions vary across ecosystems, the patterns of interactions of organisms with their environments, both living and nonliving, are shared.

Competition involves species vying for resources, while predation entails one species consuming another. Symbiosis involves long-term relationships, including parasitism (one benefits, the other suffers), mutualism (both benefit), and commensalism (one benefits, the other remains unaffected).
