Mutualism is a relationship between two organisms in which both organisms benefit from the relationship. This type of relationship is common among many organisms, including plants and fungi. It is an example of symbiosis, where living organisms interact with each other to their advantage. For example, plants use fungi as a mode of acquiring essential nutrients, while fungi benefit from the sugars provided by plants. Mutualistic relationships can also be seen between pollinators and plants, where the pollinators receive nectar as food and the plants gain pollination services. In general, mutualism can be defined as a relationship in which two species living in close proximity both benefit from the association.
