Ch 17: Interdependence of Living Systems & the Environment

About This Chapter

If you're struggling to understand the interdependence of living systems and the environment, take a look at this helpful chapter. Our lessons can help you prepare for a test, finish an assignment or catch up after missed class time.

Interdependence of Living Systems & the Environment - Chapter Summary

This informative chapter covers the interdependence of the environment and living systems. The lessons cover the role of energy in life and how energy is transformed in living organisms. You'll also look at the relationship between cellular respiration and photosynthesis. Once you complete this chapter, you should be ready to meet the following objectives:

  • Identify the reactants in the equation for cellular respiration
  • Detail energy flow, trophic levels and food chains in an ecosystem
  • Discuss the types of energy and matter changes in an ecosystem
  • Define trophic levels in a food chain
  • Explain the types and stages of ecological succession
  • Provide an example of species diversity

We've made it easy to study any time or place you'd like with these mobile-friendly text and video lessons. The lessons are accessible 24 hours a day on your mobile device or computer. For video lessons, you can view the entire lesson or use the video tabs feature to skip ahead or go back to key concepts.

8 Lessons in Chapter 17: Interdependence of Living Systems & the Environment
Energy and Life: The Transformation of Energy in Living Organisms

1. Energy and Life: The Transformation of Energy in Living Organisms

While the sun is an excellent source of energy, not all forms of life can utilize the sun's energy directly. This lesson describes how plants transform the sun's energy into potential energy stored in sugar, how living organisms utilize energy in sugar to perform work, and how the relationship between photosynthesis and cellular respiration is necessary for life.

The Relationship Between Photosynthesis & Cellular Respiration

2. The Relationship Between Photosynthesis & Cellular Respiration

The ecosystems of the world are generally in balance with one another. Animals and plants live in mutually beneficial relationships. We will examine one of these relationships: the relationship between photosynthesis and cellular respiration.

What Are the Reactants in the Equation for Cellular Respiration?

3. What Are the Reactants in the Equation for Cellular Respiration?

Why must we breathe and eat in order to stay alive? Most people know that we have to, but have you ever wondered why? This lesson investigates this through an introduction into cellular respiration.

Food Chains, Trophic Levels and Energy Flow in an Ecosystem

4. 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.

Types of Matter & Energy Changes in an Ecosystem

5. Types of Matter & Energy Changes in an Ecosystem

Ecosystems are a constant flow of matter and energy from one place to another. In this lesson, we will discuss some of the important energy and matter cycles that take place within and between ecosystems.

Trophic Levels in a Food Chain: Definition & Explanation

6. Trophic Levels in a Food Chain: Definition & Explanation

This lesson will explore the feeding relationships of organisms in an ecosystem, including food chains and food webs. The lesson will also investigate the different trophic levels of a food chain and give examples of species found at each level.

What Is Ecological Succession? - Definition, Types & Stages

7. What Is Ecological Succession? - Definition, Types & Stages

How does an ecological community develop? Ecological succession describes this process of development, identifying how the community began as well as how and when it stabilizes.

What is Species Diversity? - Definition, Importance & Examples

8. What is Species Diversity? - Definition, Importance & Examples

Have you ever wondered how many species live on Earth? Earth is full of amazing creatures. In this lesson, you will learn about the importance of species diversity. At the end, test your knowledge with a quiz.
