Who's it for?
This chapter of our Middle School Earth Science Tutoring Solution will benefit any student who is trying to learn about ecology and ecosystems and earn better grades. This resource can help students including those who:
- Struggle with understanding environmental topics, symbiotic relationships, food chains or any other ecology and ecosystems topic
- Have limited time for studying
- Want a cost effective way to supplement their Earth science learning
- Prefer learning Earth science visually
- Find themselves failing or close to failing their ecology and ecosystems unit
- Cope with ADD or ADHD
- Want to get ahead in Earth science
- Don't have access to their Earth science teacher outside of class
Why it works:
- Engaging Tutors: We make learning ecology and 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 Earth science tutor, these video lessons are thoroughly reviewed.
- Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn about the ecology and 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.
- Discover various levels of ecology
- Study conservation biology
- Explore symbiotic relationships within an ecosystem
- Learn about regions with similar ecosystems
- Explore interactions between predators and prey
- Understand acid rain, fossil fuels and the carbon cycle
- Study topics relating to food chains, ecological balance and habitat fragmentation
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.
2. 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.
3. 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.
4. 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.
5. Carrying Capacity, Migration & Dispersion
Have you ever wondered why some types of birds fly south in the winter or why some animals form territories? Watch this video to learn about a species' maximum growth capabilities, the way its members group themselves and why they might migrate to new locations every year.
6. Conservation Biology, Habitat Fragmentation, and Metapopulations
It's becoming harder to conserve large, unbroken tracts of wilderness. Is there another way for conservation biologists to ensure the survival of a species? In this lesson, you'll learn about habitat fragmentation and metapopulations.
7. Ecological Succession: From Pioneer to Climax Communities
Just as people grow and change so, too, do ecosystems. Watch this lesson to learn about ecological succession from the beginning stages of development to a community's ultimate destination, or climax.
8. How Introduced and Invasive Species Alter Ecological Balance
What happens to your block when a new neighbor moves in? Something changes, right? Now think about that on an ecological scale: what happens to an environment when a new SPECIES moves in?
9. Biomes: Desert, Tropical Rainforest, Savanna, Coral Reefs & More
Take a trip around the world and learn all about different biomes. Why can you only find certain plants and animals in specific places? What are the most fertile climates on Earth? Watch on to answer these and other questions.
10. Biomes: Tundra, Taiga, Temperate Grassland, and Coastlines
Take a trip with us in this lesson, starting in the Pacific Ocean, traveling across California through the Central Valley and up to the peaks of the Sierra Nevada mountains. We'll learn how oceans, elevation, and people can determine which types of biomes are found in different areas and check out the Earth's most massive and oldest organisms.
11. The Nitrogen Cycle, Acid Rain and Fossil Fuels
Do you know the difference between nitrite and nitrate? Do you have any clue how all the nitrogen in the atmosphere becomes usable? If you can't answer these questions, then you need to watch this lesson on the nitrogen cycle.
12. 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.
13. Microbial Ecology: History & Importance
Microbial ecology aims to study how microbes live and interact with their environment. Though this branch of study is relatively new compared to others, it is immensely important to all life on Earth. Let's take a look at how this study came to be and just why it is so important.
14. Microbial Ecology: Methods & Techniques
In this lesson, you will learn why tiny organisms are garnering ever more attention from scientists. Also learn about the methods and techniques these scientists use to figure out how crucial these tiny organisms are to life.
