Which statement about mutualisms is true?

Question

Quizplus · Accepted Answer

Mutualisms can be obligate, one-on-one relationships such as the relationship between coral and zooxanthellae, or they can be diffuse relationships that involve many species, such as the relationship between plants and their pollinators. The evolutionary consequences of mutualisms can be complex and difficult to predict, but they often involve coevolution between the interacting species. Mutualisms do not necessarily involve altruism, as both partners can benefit from the interaction.
