Foraging is the process of seeking out nutrients in the environment. It may also be defined to include the subsequent use of the resources. Some organisms, such as animals and bacteria, can navigate to find nutrients, while others, such as plants and fungi, extend outward to find nutrients. Foraging may be random, in which the organism seeks nutrients without method, or it may be systematic, in which the organism can go directly to a food source.{{Sfn|Andrews|2017|pp=83–85}} Organisms are able to detect nutrients through [[taste]] or other forms of [[nutrient sensing]], allowing them to regulate nutrient intake.{{Sfn|Simpson|Raubenheimer|2012|p=36}} [[Optimal foraging theory]] is a model that explains foraging behavior as a [[cost–benefit analysis]] in which an animal must maximize the gain of nutrients while minimizing the amount of time and energy spent foraging. It was created to analyze the foraging habits of animals, but it can also be extended to other organisms.{{Sfn|Andrews|2017|p=16}} Some organisms are specialists that are adapted to forage for a single food source, while others are generalists that can consume a variety of food sources.{{Sfn|Andrews|2017|p=98}}
