Assume that an individual foraging animal obtains the following payoffs: * when foraging alone, payoff = 8 * when in a group of 2, payoff = 16 * when in a group of 3. payoff - 12 * when in a group of 4, payoff - 10 * when in a group of 5, payoff - 6 * when in a group of 6. payoff = 4 1) Identify what the stable group size is expected to be. Then: 2) select one group size that is smaller than the stable size and explain why it is not stable, and 3) select one group size that is larger than the stable size nd explain why it is not stable. Your explanations should involve the relevant specific payoff values, and individual forager choices. (6 points total)
