3 continued Circle the word that best completes the statement. 5. Homeostasis refers to the maintenance of constant / variable internal conditions. An animal s behavior can help to maintain homeostasis, because many behaviors are responses to associations / stimuli that affect an animal s well-being. For example, if an animal gets too hot, it might move to a shady location. 6. Kinesis is an increase / decrease in random movement, and taxis is a movement in a random / particular direction. MAIN IDEA: Internal and external stimuli usually interact to trigger specific behaviors. Choose a word or words from the box below to complete the sentence. external internal hormones physiological 7. Some behaviors can be triggered by a single stimulus, but most behaviors occur in response to a variety of and stimuli. 8. An external stimulus, such as a change in day length, might cause an animal to secrete specific. 9. These hormones act as internal signals that cause other changes. These changes, in turn, cause the animal to be more likely to respond to another external stimulus. MAIN IDEA: Some behaviors occur in cycles. Fill in the blank with the word or phrase that best completes the sentence. 10. A circadian rhythm is a daily cycle of activity that occurs over a -hour period of time. 11. is a behavior in which an animal avoids extreme temperatures by entering into a dormant state. 12. is a behavior in which an animal moves from one location to another (often a long distance) to avoid harsh climate conditions. Vocabulary Check 13. The word circadian comes from a Latin word that means circle. A circadian rhythm is a circular pattern of activity, because it repeats every.

6 continued Vocabulary Check Circle the word that best completes the statement. 13. A releaser is a(n) imitation / signal that causes an animal to run through a behavior. 14. Habituation occurs when an animal learns to ignore / notice a repeated stimulus, even when it would normally trigger an innate response. 15. Imprinting is a type of learning where an animal learns to imitate / recognize another animal, such as its parents, siblings, or offspring. 16. Imitation occurs when an animal learns by observing / ignoring the behaviors of other animals. Holt McDougal Biology 5 Animal Behavior Section 2: Instinct and Learning
7 Section 3: Evolution of Behavior KEY CONCEPT Every beneficial behavior has costs and benefits. VOCABULARY survivorship territoriality optimal foraging MAIN IDEA: Even beneficial behaviors have associated costs. Circle the letter(s) for the best choices. 1. What are the two most important benefits of behavior? a. a better chance of survival b. a greater chance of finding food c. decreased isolation d. increased rates of reproduction e. more control of habitat Circle the word that best completes the following sentences, which describe the behavioral costs in the table. Place the number for the sentences into the appropriate box in the table. 2. Every behavior takes time, and this time can / cannot be used on a different behavior. 3. Many behaviors expose / protect an animal to / from injury or death. 4. Every behavior uses up ADP / ATP, and this energy is therefore not available for other behaviors. Cost of Behavior Energy costs Description 5. Opportunity costs 6. Risk costs 7. Holt McDougal Biology 6 Animal Behavior Section 3: Evolution of Behavior
8 continued MAIN IDEA: Animals perform behaviors that outweigh their costs. Fill in the blank with the word or phrase that best completes the sentence. 8. is the control of a specific area, or territory, by one or more individuals of a species. Place a check mark in the appropriate box to indicate whether each statement is a cost or a benefit of territorial behavior or of foraging. Territorial Behavior Foraging Behavior Cost Benefit Cost Benefit 9. Energy and time that could have been used for behaviors unrelated to defense 10. Energy used to search for, catch and eat food, as well as the risk of being captured by a predator 11. Amount of energy gained (calories) 12. Ability to control the resources within an animal s territory Circle the word that best completes the statement. 13. Optimal foraging is the theory that natural selection should favor foraging behaviors that get animals the least / most calories for the least / most cost. Vocabulary Check Circle the word that best completes the statement. 14. Survivorship is the number of individuals that reproduce / survive from one year to the next. 15. Territoriality refers to behavior in which an individual or group attacks / defends its territory. Holt McDougal Biology 7 Animal Behavior Section 3: Evolution of Behavior
9 continued Be Creative 16. In the box below, draw a cartoon that illustrates the costs and benefits of either territoriality or optimal foraging. Holt McDougal Biology 8 Animal Behavior Section 3: Evolution of Behavior
10 Section 4: Social Behavior KEY CONCEPT Social behaviors enhance the benefits of living in a group. VOCABULARY pheromone inclusive fitness eusocial altruism kin selection MAIN IDEA: Living in groups also has benefits and costs. Use the letters for the following phrases to complete the table about the costs and benefits of living in a group. a. higher chance of contracting diseases b. improved foraging c. increased visibility d. more competition e. reduced chance of predation f. reproductive assistance 1.

11 continued Circle the word that best completes the statement. 7. Courtship displays are behaviors most often used by male / female members of a species to attract males / females. For example, jumping spiders dance and bowerbirds build bowers. 8. Scientists think that courtship displays might have an evolutionary function. A female might use the courtship display to judge the condition of her potential mate or the quality of his ideas / genes. 9. Defensive behaviors are aggressive behaviors used to advertise / protect the individual and/or the group. Two examples are mobbing and keeping watch. MAIN IDEA: Some behaviors benefit other group members at a cost to the individual performing them.

Males / females are haploid and males / females are diploid. Vocabulary Check Fill in the blank with the word or phrase that best completes the sentence. 17. A is a chemical released by an animal that affects the behavior of other individuals of the same species. 18. A(n) behavior is one that benefits the other members of a group but does not directly benefit the individual performing the behavior.
