Animal Behavior Chapter 44 Section 1 Pg. 886-892
A Closer Look 1. Identify the: Predator Prey 2. Describe the response to predation. 3. How does this action help their family? 4. Explain how might this benefit the population.
Behavior • What is behavior? • What an animal does and how it does it • An animal’s reaction to stimuli
Essential Questions • What causes the behavior? • Why does a behavior occur? • How does it affect the organisms survival and reproduction?
Survival of the Fittest • Behavior ensures that the individual or group survives to pass on their genes to the next generation • Ex. Male lions kill other baby lions that don’t have their DNA • All behavior has some genetic basis • Ability to learn behavior is inherited • Behavior is modified by the environment
Types of Behavior • Innate (Instincts) • Inherited actions that are performed effectively from birth • Ex. Spiders building webs, cats cleaning • Learned • Actions that change with experience
Learned Behavior 1. Habituation Organism learns to ignore harmless stimuli • Squirrels stop responding to alarm calls if not followed by an attack • You no longer smell a perfume throughout the day How can this help survival and ensure reproduction?
2. Classical Conditioning Animal learns to associate a response with a certain stimulus • Ivan Pavlov’s dog

3. Operant Conditioning Organism associates some operation (action) with a reward/punishment • Test animals learned to pull levers that yielded food and avoid those that caused electrical shock
4. Problem Solving and Reasoning Ability to solve a problem that has not been encountered before
Group Behaviors • 1. Can be cyclic and develop to changes in the environment • Migration • Hibernation
2. Interaction between 2 or more animals • Flocking • Schooling • Herding • Cooperative hunting • Altruism: an individual sacrifices his survival for the benefit of the group (ex. Prairie dog)
