TPO 48 - Question 4
Optimal Foraging
Food provides animals with the energy they need to survive. However, animals also lose energy in the process of obtaining, or foraging, for food. Therefore, in order to conserve energy, many animals behave in ways that minimize the energy they expend in the foraging process while at the same time maximizing their nutritional benefits. This energy-efficient approach to obtaining food is known as optimal foraging. The practice of optimal foraging allows animals to expend the least possible amount of energy while at the same time obtaining prey with high food value that will provide them with necessary nutrients.
