WebOptimal foraging theory posits that an organism should seek to maximize its intake of nutrients, while minimizing expenditures, such as time and energy [91]. For example, a key … Optimal foraging theory (OFT) is a behavioral ecology model that helps predict how an animal behaves when searching for food. Although obtaining food provides the animal with energy, searching for and capturing the food require both energy and time. To maximize fitness, an animal adopts a foraging strategy that provides the most benefit (energy) for the lowest cost, maximizing the ne… trumpf download https://andylucas-design.com
