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. Foraging theory is a branch of behavioral ecology that studies the foraging behavior of animals in response to the environment where the animal lives.Behavioral ecologists use economic models to understand foraging; many of these models are a type of optimality model.he theory scientists use to understand group foraging is called the Ideal free distribution. This is the null model for thinking about what would draw animals into groups to forage and how they would behave in the process.
Gleaning is the process of collecting excess farm crops for distribution, but is being used to describe the more general practice of food recovery, where many kinds of food, including packaged perishable and non-perishable goods, are collected and distributed to the hungry and poor.he Society of St. Andrew, the largest gleaning group in the U.S. , harvests or gathers 30 million pounds of food each year to distribute to a network of pantries.
