Foraging strategy must provide the most benefit for the lowest cost – it is a balance between nutritional value and energy required. The currency of optimal foraging theory is energy because it is an essential component for organisms, but it is also the downfall of optimal foraging theory in regard to archaeology. [26]
Foraging is searching for wild food resources. It affects an animal's fitness because it plays an important role in an animal's ability to survive and reproduce. [1] Foraging theory is a branch of behavioral ecology that studies the foraging behavior of animals in response to the environment where the animal lives.
The marginal value theorem (MVT) is an optimality model that usually describes the behavior of an optimally foraging individual in a system where resources (often food) are located in discrete patches separated by areas with no resources. Due to the resource-free space, animals must spend time traveling between patches.
As an optimal foraging model, the Ideal Free Distribution predicts that the ratio of individuals between two foraging sites will match the ratio of resources in those two sites. This prediction is similar to the Matching Law of individual choice, which states that an individual's rate of response will be proportional to the positive ...
The basic tenet of the DRM is that the intake of energy by an animal passes through two consecutive processes, food ingestion or foraging, and food digestion. Optimal foraging theory describes the diet selection if the food ingestion rate is the limiting factor. The DRM describes diet selection and foraging behavior if digestion is the rate ...

Risk sensitive foraging is based on experimental evidence that the net energy budget level of an animal is predictive of type of foraging activity an animal will employ. [1] Experimental evidence has indicated that individuals will change the type of foraging strategy that they use depending on environmental conditions and ability to meet net ...
