Optimal foraging theory means that turning down food is sometimes more efficient than eating it - but even then, what’s “wasted” doesn’t necessarily go to waste. LEARN MORE ************** To learn more about this topic, start your googling with these keywords: Foraging: to search widely for food. Optimal Foraging Theory: A behavioral model that describes how an animal should behave when searching for food. Surplus Killing: a common behavior exhibited by predators, in which they kill more prey than they can immediately eat and then cache or abandon the remainder.
