Ch 28: Life & Zoological Sciences

About This Chapter

Utilize this chapter to learn all about primates and food chains by watching 5- to 10-minute video lessons, then evaluate how much you remember about animal reproduction through the brief self-assessments. This chapter will help you remember all you need to know about life and zoological sciences.

Life & Zoological Sciences - Chapter Summary

In this chapter, you can watch brief video lessons about what hominids eat. Quiz yourself on predator and pray interactions by taking an end of the lesson quiz. This chapter's study resources will refresh your memory of the following items:

  • Traits of birds, mammals, and amphibians
  • Primates
  • Diet of hominids
  • Definition of vertebrates and invertebrates
  • Food chains and energy flow
  • Inborn and learned animal behavior
  • Predator/prey interactions
  • Chemical and electrical signals of animals' communication
  • Animal reproduction and populations

If you would like to create a list of the vocabulary words for the lessons, you can access them by clicking the transcript link. You do not need to watch the entire videos to review certain parts. The timeline at the bottom of each video will allow you to jump to the parts of the videos you need.

Birds: Traits, Types & Importance

1. Birds: Traits, Types & Importance

Have you ever wanted to be a bird? Or thought about flying like a bird? In this lesson, we're going to learn about why birds are birds, how they fly, and why they're important to us both ecologically and economically.

Mammals: Traits, Behavior & Grouping

2. Mammals: Traits, Behavior & Grouping

Ever wondered what the largest mammal on Earth was? Or what traits connect mammals together? In this lesson, you will discover the basic traits of mammals, some of their behavior, and how they are grouped by scientists. Read on!

Amphibians: Traits, Types & Roles

3. Amphibians: Traits, Types & Roles

Amphibians. Does the word conjure up images of slimy frogs and salamanders? Or perhaps a case of warts after handling a toad? Amphibians are a fascinating group of animals that we don't see very often. Find out more in this lesson.

Primates and Human Origin

4. Primates and Human Origin

You probably know that you are a primate, just like gorillas and monkeys. But you may be surprised to find out how long primates have been around and how many of them are still living on Earth, which are covered in this lesson.

Hominids: Traits, Diet & Behavior

5. Hominids: Traits, Diet & Behavior

This lesson will help you to better understand hominids. We'll discuss the characteristics, diet and behavior of hominids, in order to give you a better idea of what this species is like.

Vertebrates: Definition, Features & Classification

6. Vertebrates: Definition, Features & Classification

Vertebrates are an interesting collection of animals, including humans, that have evolved over millions of years. Birds, reptiles, amphibians, mammals and even fish are included in the vertebrate category. Find out more here!

Invertebrates: Definition & Examples

7. Invertebrates: Definition & Examples

From bees to lobsters and octopi to cockroaches, invertebrates are everywhere. This lesson introduces them as a major group within biology and discusses their relationship with the human race.

Food Chains, Trophic Levels and Energy Flow in an Ecosystem

8. Food Chains, Trophic Levels and Energy Flow in an Ecosystem

In this lesson, you'll learn about food chains, food webs, and the different roles that organisms play in an ecosystem. You'll also learn about how energy flows through an ecosystem.

Animal Behavior: Innate vs. Learned

9. Animal Behavior: Innate vs. Learned

There are some things that animals are born knowing how to do. These behaviors are innate. They are different than learned behaviors, which an animal must pick up through training, observation or experience. Learn more about these types of behaviors.

Predator/Prey Interactions, Camouflage, Mimicry & Warning Coloration

10. Predator/Prey Interactions, Camouflage, Mimicry & Warning Coloration

You probably know that skunks can be quite stinky, bees sting and monarch butterflies are pretty, but do you know why? This lesson will introduce you to the reasons why some animals look or act the way they do and how these things relate to the predator/prey relationship.

How Animals Communicate: Chemical, Visual & Electrical Signals

11. 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.

Overview of Animal Reproduction and Development

12. Overview of Animal Reproduction and Development

At this stage in life, you likely know where babies come from. However, did you know that some animals can make clones of themselves and reproduce sexually too? In this lesson, you'll learn more about sexual reproduction and early vertebrate development.

Carrying Capacity within Animal Populations

13. Carrying Capacity within Animal Populations

How many animals can an ecosystem support? This is the question scientists ask themselves when they are trying to determine the carrying capacity of an area. Learn how scientists evaluate factors that limit carrying capacity.
