Ecosystems, Habitats and Ecological Niches

6. 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.

What Is a Biome? - Definition & Types

7. What Is a Biome? - Definition & Types

If you travel around the world, you can visit dry deserts with lots of cacti, the cold arctic with little plant life, or humid tropical rainforests. These different regions on Earth are all called biomes. Continue reading to learn about different types of biomes.

Food Chains, Trophic Levels and Energy Flow in an Ecosystem

8. 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.

Animal Behavior: Innate vs. Learned

9. Animal Behavior: Innate vs. Learned

There are some things that animals are born knowing how to do. These behaviors are innate. They are different than learned behaviors, which an animal must pick up through training, observation or experience. Learn more about these types of behaviors.

Instinct: Definition & Explanation

10. Instinct: Definition & Explanation

All species in the animal kingdom - from bears to whales to birds to humans - exhibit instinctual behavior. Learn how instinct works across species, see some examples, and then test your knowledge with a short quiz.
