Question 1

Which of the following best describes the main focus of organismal ecology?

Accepted Answer

It studies the physiological and behavioral adaptations that enable individual organisms to survive in their environment.

Question 2

A researcher observes that a certain species of bird removes eggshells from its nest immediately after hatching. According to Tinbergen’s experiments, what is the adaptive significance of this behavior?

Accepted Answer

It reduces the risk of predation by making the nest less conspicuous to predators.

Question 3

Which of the following is an example of a fixed action pattern (FAP)?

Accepted Answer

A goose rolling an egg back into its nest after it has been displaced.

Question 4

Which of the following best explains the difference between classical and operant conditioning?

Accepted Answer

Classical conditioning pairs a neutral stimulus with an involuntary response, while operant conditioning reinforces behavior with rewards or punishments.

Question 5

A blue jay eats a monarch butterfly and subsequently vomits. In the future, the blue jay avoids eating monarch butterflies. This is an example of:

Accepted Answer

Associative learning

Question 6

Which of the following statements about the fosB gene in mice is supported by experimental evidence?

Accepted Answer

The presence of functional fosB alleles is necessary for nurturing behavior in female mice.

Question 7

Which of the following best describes optimal foraging theory?

Accepted Answer

Animals behave in a way that maximizes the net energy gained per unit time spent foraging.

Question 8

A shore crab prefers to eat intermediate-sized mussels rather than the largest or smallest available. According to optimal foraging theory, why is this the case?

Accepted Answer

Intermediate-sized mussels provide the highest rate of energy return relative to the effort required to open them.

Question 9

Which of the following is an example of cognitive learning in animals?

Accepted Answer

A chimpanzee stacking boxes to reach a suspended banana without prior training.

Question 10

Which of the following best illustrates the concept of nature versus nurture in animal behavior?

Accepted Answer

Birds are genetically programmed to learn songs, but will only sing the correct song if they hear it during development.

Question 11

Which of the following is NOT a characteristic of innate behavior?

Accepted Answer

It is modified by experience.

Question 12

Which of the following best describes the role of the nervous and endocrine systems in animal behavior?

Accepted Answer

They transmit internal signals, such as hormones and neurotransmitters, that help drive behavioral responses to stimuli.

Question 13

Which of the following is an example of nonassociative learning?

Accepted Answer

A sea slug decreasing its withdrawal response after repeated gentle touches.

Question 14

Which of the following equations best represents the concept of optimality theory in behavioral ecology?

Accepted Answer

$$Benefit - Cost = Net\;Gain$$

Question 15

In a classical conditioning experiment, a dog learns to salivate when it hears a bell because the bell has been repeatedly paired with food. In this scenario, what is the bell considered?

Accepted Answer

Conditioned stimulus

Question 16

Which of the following best describes the main difference between population ecology and community ecology?

Accepted Answer

Population ecology studies the dynamics of a single species, while community ecology examines interactions among multiple species.

Question 17

Which of the following is an example of operant conditioning?

Accepted Answer

A rat pressing a lever to receive food after learning the association.

Question 18

Which of the following best describes the process of habituation?

Accepted Answer

An animal decreases its response to a repeated, harmless stimulus.

Question 19

Which of the following best explains why learned behaviors can be advantageous in a dynamic environment?

Accepted Answer

Learned behaviors allow animals to adapt to changing conditions and novel challenges.
