About This Chapter
ILTS Biology: Social Behavior of Animals - Chapter Summary
The lessons in this chapter offer a chance to review social behavior in animals, and they provide some theories to explain them. Concepts covered here can aid in your study for ILTS Biology test questions on subjects such as:
- Innate and learned behavioral traits
- Animals' social behavior
- Social systems and individual fitness
- Theory of demographic transition
- The circadian rhythms of animals and plants
- Ways that animals communicate
- Stages of family life and traditions surrounding them
You can watch these short video lessons 24/7 on a computer, smartphone or tablet. Read through the lesson transcripts to get an idea of the main topics, and use the links in the Timeline to return to specific parts of the video for review. Lesson quizzes and a chapter exam let you assess your learning, and there's a worksheet of quiz questions you can print out for offline study.
ILTS Biology: Social Behavior of Animals Chapter Objectives
Illinois requires passing the ILTS Biology test as one of the conditions for teacher certification. The exam consists of 125 multiple-choice questions, divided into six subareas. The topics covered in this Social Behavior of Animals chapter are part of the life science subarea. The lesson quizzes and the chapter exam in this study guide also consist of multiple-choice questions, so completing them will be good practice for what you'll face on exam day.
1. Innate & Learned Behavior
We all respond to different situations with some type of behavior. Some of these are innate and others are learned. This lesson will help differentiate between the two.
2. Social Behavior of Animals
Why does that squirrel flap its tail when your dog gets close to the tree? Or why are you more willing to donate a kidney to a sibling than a stranger? Learn about these and other behaviors that come along with living in a social group.
3. Social Systems vs. Individual Fitness: The Queen/Worker Relationship
The queen bee rules her hive while others take care of her needs. This form of behavior may seem odd, but it can be explained by looking into social systems and fitness.
4. The Theory of Demographic Transition: Overview
Populations change over time. The growth or decline of a population can have an effect on the quality of life for people within that population. In this lesson, you'll learn about the theory of demographic transition, which is a model used to study and predict population changes.
5. The Circadian Rhythm
You wake up in the morning and go to sleep at night. But some animals do the opposite: wake at night and sleep during the day. What determines the time of day you're active is your circadian rhythm, an internal clock that keeps daily time for you.
6. How Animals Communicate: Chemical, Visual & Electrical Signals
Animals use a variety of different signals to communicate with each other. In this lesson you'll identify the different types of communication signals and the situations in which they might be most useful.
7. Family Life Stages and Traditions: Courtship, Marriage, Child Rearing & Aging
In this lesson, we discuss the four stages of traditional family life that sociologists study. Although the concept of family has changed with time, these four stages remain prominent in our culture.
