PLACE Elementary Education: Life Science - Chapter Summary

This chapter ensures you're prepared to answer life science questions on the PLACE Elementary Education assessment. By reviewing these lessons, you will gain the knowledge needed to do the following:

  • Discuss basic needs of living organisms, and define and describe biodiversity
  • Provide details about ecosystems, habitats and ecological niches
  • Describe interspecific competition, competitive exclusion and niche differentiation
  • Share information about predator/prey interactions, camouflage, mimicry and warning coloration
  • Define symbiotic relationships, photosynthesis and respiration
  • Analyze genetics, evolution and evolutionary change

Lesson instructors are subject-matter experts who provide the important definitions, explanations and examples you need to fully comprehend life science. Review the lessons in any sequence and at a frequency that suits you best.

PLACE Elementary Education: Life Science Chapter Objectives

Educators in Colorado take the PLACE Elementary Education assessment to secure the licensure needed to teach students in elementary classrooms. The test consists of 6 subareas that examine your comprehension of various elementary subjects and teaching strategies. Most PLACE tests consist of 100 multiple-choice questions and last four hours and 30 minutes. Passing requires earning a minimum score of 220.

Use the lessons in this chapter to prepare for questions in the science subarea of the test. You may be asked to understand the basic concepts and principles of life science. Gauge your comprehension of the lessons by taking self-assessment quizzes and a chapter exam. If you have any questions about this chapter, submit them to our experts.

Living Organisms: Basic Needs

1. Living Organisms: Basic Needs

There are many types of living organisms on Earth. But what makes us all the same is our basic needs for survival, which is a shorter list than you might think!

What is Biodiversity? - Definition and Relation to Ecosystem Stability

2. What is Biodiversity? - Definition and Relation to Ecosystem Stability

Imagine making a list of all of the species you have ever heard of; it would be an enormous list! There are many different species on this planet. This lesson will explore the diversity of species, as well as the different types of diversity and how diversity of life is essential for maintaining healthy ecosystems.

Ecosystems, Habitats and Ecological Niches

3. Ecosystems, Habitats and Ecological Niches

Check out this video lesson to understand the many complex aspects of an ecosystem. See how animals live in habitats and survive amongst their surroundings.

Interspecific Competition, Competitive Exclusion & Niche Differentiation

4. Interspecific Competition, Competitive Exclusion & Niche Differentiation

What happens when two similar species that consume the same resources occupy the same space? Interspecific competition, that's what! Watch our video lesson to learn about the outcomes of this ecological battle.

Predator/Prey Interactions, Camouflage, Mimicry & Warning Coloration

5. 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.

Symbiotic Relationships: Mutualism, Commensalism & Parasitism

6. Symbiotic Relationships: Mutualism, Commensalism & Parasitism

If your cat or dog has ever had fleas, you've witnessed symbiosis in action. In this lesson, learn the many types of symbiosis in biology, and how these relationships can have a positive, negative, or neutral effect on the individual species.

Photosynthesis: Definition & Reactions

7. Photosynthesis: Definition & Reactions

Some people may falsely assume plants to be weaker than animals. However, plants and a few other organisms harness light energy from the sun to feed the rest of us. This lesson will introduce you to how they do it.

What is Respiration? - Definition, Process & Equation

8. What is Respiration? - Definition, Process & Equation

Respiration is a metabolic process common to all living things. Here, you will learn the definition, location, processes, and formula for cellular respiration. At the end, you can test your knowledge with a short quiz.

Genetics: Heredity, Traits & Chromosomes

9. Genetics: Heredity, Traits & Chromosomes

We view manipulation of genes in our crops and livestock as a recent development. Yet, man has been manipulating the genetic makeup of his food for thousands of years through cultivation and breeding. This lesson will begin to help you understand how genetics works.

Theories of Evolution: Lamarck vs. Darwin

10. Theories of Evolution: Lamarck vs. Darwin

We'll look at the interplay between population genetics and environment. Are traits individually acquired or do entire populations evolve? The flying hamsters and a few other notable experiments will provide the answers.

Evolutionary Change: Definition and Forms

11. Evolutionary Change: Definition and Forms

You've probably heard of Charles Darwin and evolution. We know that evolution is change over time, but here we will look at how these changes may have occurred during Earth's history.
