In game theory, what is the term for a situation where two organisms have conflicting interests and each organism's best strategy depends on the strategy of the other?

  1. Nash Equilibrium

  2. Prisoner's Dilemma

  3. Tragedy of the Commons

  4. Evolutionarily Stable Strategy


Correct Option: B
Explanation:

The Prisoner's Dilemma is a classic game theory model that illustrates the conflict between individual and collective interests.

In a predator-prey relationship, what is the term for the strategy where the predator targets the prey that is easiest to capture, regardless of its quality?

  1. Optimal Foraging Theory

  2. Evolutionarily Stable Strategy

  3. Tit-for-Tat Strategy

  4. Nash Equilibrium


Correct Option: A
Explanation:

Optimal Foraging Theory predicts that predators will target prey that provide the greatest net benefit, considering factors such as capture difficulty and nutritional value.

In a mutualistic relationship, what is the term for the strategy where each organism provides a benefit to the other, and both organisms benefit from the interaction?

  1. Evolutionarily Stable Strategy

  2. Tit-for-Tat Strategy

  3. Prisoner's Dilemma

  4. Nash Equilibrium


Correct Option: A
Explanation:

An Evolutionarily Stable Strategy is a strategy that cannot be invaded by any other strategy, meaning that it is stable over time in a population.

In a game theory model of cooperation, what is the term for the strategy where an organism cooperates with others, even if it means sacrificing some of its own resources, in the expectation that it will ultimately benefit from the cooperation of others?

  1. Tit-for-Tat Strategy

  2. Prisoner's Dilemma

  3. Nash Equilibrium

  4. Evolutionarily Stable Strategy


Correct Option: A
Explanation:

The Tit-for-Tat Strategy is a cooperative strategy where an organism cooperates initially and then responds to the actions of others, cooperating if they cooperate and defecting if they defect.

In a game theory model of competition, what is the term for the strategy where an organism tries to maximize its own payoff, even if it means harming others?

  1. Nash Equilibrium

  2. Prisoner's Dilemma

  3. Tragedy of the Commons

  4. Evolutionarily Stable Strategy


Correct Option: A
Explanation:

A Nash Equilibrium is a set of strategies, one for each player, where no player can improve their payoff by changing their strategy while the other players keep their strategies unchanged.

In a game theory model of resource allocation, what is the term for the strategy where organisms compete for a limited resource, and the organism that invests the most resources is most likely to win the competition?

  1. Evolutionarily Stable Strategy

  2. Tit-for-Tat Strategy

  3. Prisoner's Dilemma

  4. Tragedy of the Commons


Correct Option: D
Explanation:

The Tragedy of the Commons is a situation where individuals acting in their own self-interest overuse a shared resource, leading to its depletion.

In a game theory model of signaling, what is the term for the strategy where an organism sends a signal to another organism, and the signal is costly to produce but provides information that benefits the receiver?

  1. Evolutionarily Stable Strategy

  2. Tit-for-Tat Strategy

  3. Prisoner's Dilemma

  4. Handicap Principle


Correct Option: D
Explanation:

The Handicap Principle states that costly signals are reliable indicators of quality, because organisms would not invest in costly signals unless they were confident that they had something to gain.

In a game theory model of mate choice, what is the term for the strategy where an organism chooses a mate based on their physical attractiveness, even if they are not the best mate in terms of other qualities?

  1. Evolutionarily Stable Strategy

  2. Tit-for-Tat Strategy

  3. Prisoner's Dilemma

  4. Good Genes Hypothesis


Correct Option: D
Explanation:

The Good Genes Hypothesis states that mate choice based on physical attractiveness is a way for organisms to choose mates with good genes.

In a game theory model of parental care, what is the term for the strategy where a parent invests more resources in offspring that are more likely to survive and reproduce?

  1. Evolutionarily Stable Strategy

  2. Tit-for-Tat Strategy

  3. Prisoner's Dilemma

  4. Trivers-Willard Hypothesis


Correct Option: D
Explanation:

The Trivers-Willard Hypothesis states that parents should invest more resources in offspring that are more likely to survive and reproduce.

In a game theory model of social behavior, what is the term for the strategy where an organism helps another organism, even if it means sacrificing some of its own resources, in the expectation that it will ultimately benefit from the help of others?

  1. Evolutionarily Stable Strategy

  2. Tit-for-Tat Strategy

  3. Prisoner's Dilemma

  4. Reciprocal Altruism


Correct Option: D
Explanation:

Reciprocal Altruism is a strategy where an organism helps another organism in the expectation that it will be helped in return.

In a game theory model of territoriality, what is the term for the strategy where an organism defends a territory from other organisms, even if it means risking injury or death?

  1. Evolutionarily Stable Strategy

  2. Tit-for-Tat Strategy

  3. Prisoner's Dilemma

  4. Territorial Defense Hypothesis


Correct Option: D
Explanation:

The Territorial Defense Hypothesis states that territoriality is a strategy that allows organisms to defend their resources from other organisms.

In a game theory model of migration, what is the term for the strategy where an organism moves from one location to another in search of better resources?

  1. Evolutionarily Stable Strategy

  2. Tit-for-Tat Strategy

  3. Prisoner's Dilemma

  4. Migration Hypothesis


Correct Option: D
Explanation:

The Migration Hypothesis states that migration is a strategy that allows organisms to escape from harsh conditions or to find better resources.

In a game theory model of cooperation, what is the term for the strategy where an organism cooperates with others, even if it means sacrificing some of its own resources, in the expectation that it will ultimately benefit from the cooperation of others?

  1. Evolutionarily Stable Strategy

  2. Tit-for-Tat Strategy

  3. Prisoner's Dilemma

  4. Reciprocal Altruism


Correct Option: D
Explanation:

Reciprocal Altruism is a strategy where an organism helps another organism in the expectation that it will be helped in return.

In a game theory model of competition, what is the term for the strategy where an organism tries to maximize its own payoff, even if it means harming others?

  1. Nash Equilibrium

  2. Prisoner's Dilemma

  3. Tragedy of the Commons

  4. Evolutionarily Stable Strategy


Correct Option: A
Explanation:

A Nash Equilibrium is a set of strategies, one for each player, where no player can improve their payoff by changing their strategy while the other players keep their strategies unchanged.

In a game theory model of resource allocation, what is the term for the strategy where organisms compete for a limited resource, and the organism that invests the most resources is most likely to win the competition?

  1. Evolutionarily Stable Strategy

  2. Tit-for-Tat Strategy

  3. Prisoner's Dilemma

  4. Tragedy of the Commons


Correct Option: D
Explanation:

The Tragedy of the Commons is a situation where individuals acting in their own self-interest overuse a shared resource, leading to its depletion.
