5.      For robins small worms contain 25 calories of energy, cost 10 calories and take 2 minutes to harvest.  For the same birds medium worms contain 50 calories and cost 15 calories and take 3 minutes to harvest.  Large worms contain 75 calories, cost 30 calories and take 5 minutes to harvest.  Based on optimal foraging theory, what sized worms should robins favor?  Explain your logic!

The optimal foraging theory states that animals want to consume the most energy per unit of time. The robins would favor the medium worms because they provide 11.67 calories per min, opposed to 7.5 calories per min for the small worms and 9 calories per minute for the large worms.
