Ch 13: Introduction to Ecosystems - Middle School Life Science: Homeschool Curriculum

About This Chapter

The Introduction to Ecosystems unit of this Middle School Life Science Homeschool course is designed to help homeschooled students learn about types of ecosystems. Parents can use the short videos to introduce topics, break up lessons and keep students engaged.

Who's it for?

This unit of our Middle School Life Science Homeschool course will benefit any student who is trying to learn about ecosystems. There is no faster or easier way to learn about ecosystems. Among those who would benefit are:

  • Students who require an efficient, self-paced course of study to learn about global ecology, food systems, carbon storage, fossil fuels and biodiversity.
  • Homeschool parents looking to spend less time preparing lessons and more time teaching.
  • Homeschool parents who need a life science curriculum that appeals to multiple learning types (visual or auditory).
  • Gifted students and students with learning differences.

How it works:

  • Students watch a short, fun video lesson that covers a specific unit topic.
  • Students and parents can refer to the video transcripts to reinforce learning.
  • Short quizzes and an Introduction to Ecosystems unit exam confirm understanding or identify any topics that require review.

Introduction to Ecosystems Unit Objectives:

  • Understand how ecosystems, ecology and the environment are connected.
  • Learn about animal habitats and how species fit into ecosystems.
  • Define global ecology.
  • Get an overview of biodiversity in relationship to ecosystems.
  • Study energy flow, food chains and trophic levels within an ecosystem.
  • Analyze carbon cycles and storage.
  • Review climate conditions, such as greenhouse gases, fossil fuels and global warming.
  • Discover how animals or plants resemble other objects, camouflage themselves and interact with each other.
  • Learn how organisms work together or interact with each other in an ecosystem.

The Environment, Levels of Ecology and Ecosystems

1. The Environment, Levels of Ecology and Ecosystems

Do you know the difference between an environment and an ecosystem? In this lesson, you'll find out what makes an environment, and what makes an ecosystem. You'll also learn what ecology is and some of the ways that scientists study ecology using organisms, populations, communities, ecosystems and even the entire biosphere.

Ecosystems, Habitats and Ecological Niches

2. 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.

Global Ecology: Definition and Overview

3. Global Ecology: Definition and Overview

A large oil spill in the middle of the ocean and the release of greenhouse gases into the atmosphere are examples of environmental problems that can influence the entire planet. This lesson will explore the study of environmental problems occurring on a global scale, including the impact of globalization and current major global environmental problems.

What is Biodiversity? - Definition and Relation to Ecosystem Stability

4. 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.

Food Chains, Trophic Levels and Energy Flow in an Ecosystem

5. 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.

The Carbon Cycle and Long-Term Carbon Storage

6. The Carbon Cycle and Long-Term Carbon Storage

All living organisms have a role in the carbon cycle. Do you know you understand how humans, animals and plants use carbon? This lesson will introduce you to the carbon cycle and explain how it functions on a global scale.

Fossil Fuels, Greenhouse Gases, and Global Warming

7. Fossil Fuels, Greenhouse Gases, and Global Warming

In this video lesson, you'll learn what roles fossil fuels and greenhouse gases play in global warming, as well as what life on Earth can expect due to rising carbon dioxide levels within Earth's atmosphere.

Predator/Prey Interactions, Camouflage, Mimicry & Warning Coloration

8. 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

9. 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.
