Ch 13: Introduction to Ecosystems: Tutoring Solution

About This Chapter

The Introduction to Ecosystems chapter of this Middle School Life Science Tutoring Solution is a flexible and affordable path to learning about ecosystems. These simple and fun video lessons are each about five minutes long, and they teach all of the topics involving ecosystems required in a typical middle school life science course.

How it works:

  • Begin your assignment or other life science work.
  • Identify the ecosystems concepts that you're stuck on.
  • Find fun videos on the topics you need to understand.
  • Press play, watch and learn!
  • Complete the quizzes to test your understanding.
  • As needed, submit a question to one of our instructors for personalized support.

Who's it for?

This chapter of our Middle School Life Science Tutoring Solution will benefit any student who is trying to learn about ecosystems and earn better grades. This resource can help students including those who:

  • Struggle with understanding ecological levels, biodiversity, food chains or any other ecosystems topic
  • Have limited time for studying
  • Want a cost effective way to supplement their science learning
  • Prefer learning about science visually
  • Find themselves failing or close to failing their ecosystems unit
  • Cope with ADD or ADHD
  • Want to get ahead in middle school life science
  • Don't have access to their science teacher outside of class

Why it works:

  • Engaging Tutors: We make learning about ecosystems simple and fun.
  • Cost Efficient: For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.
  • Consistent High Quality: Unlike a live science tutor, these video lessons are thoroughly reviewed.
  • Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn about ecosystems on the go!
  • Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.

Learning objectives

  • Examine the principles of ecology
  • Distinguish between population and community ecology
  • Explore ecological niches and habitats
  • Define global ecology and discuss its importance
  • Explain biodiversity with relation to ecosystem stability
  • Learn about the trophic levels and food chains within ecosystems
  • Understand the purpose of the carbon cycle
  • Discover the relationships between greenhouse gases, fossil fuels and global warming
  • Define co-evolution, and examine the interactions between prey and predator
  • Discuss parasitism, commensalism and mutualism

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.

Ecosystem Ecology: Definition & Explanation

10. Ecosystem Ecology: Definition & Explanation

What powers life? How much energy do animals get from eating plants? What short- and long-term effects will climate change have on our environment? Asking questions such as these help ecologists better understand ecosystems and the processes within them.
