About This Chapter
Fundamentals of Ecology - Chapter Summary
This chapter is a fantastic review of the most essential topics of ecology. The major topics you will review are ecosystems and habitats. Within different ecosystems, there are unique relationships between living beings, including the food chains and the species who are the predators and the prey. You'll also investigate multiple types of symbiotic relationships and the differences between ecosystems, habitats, and ecological niches. After completing this chapter, you should be able to:
- Understand the hierarchical classification of organisms
- Know how to identify an organism with binomial nomenclature
- Explain how energy moves through trophic levels in a food chain
- Contemplate the roles of different organisms in particular habitats
- Discuss adaptations for prey, including bright coloring, camouflage, and mimicry
- Provide examples of mutualism, commensalism, and parasitism
You can view these lessons through our vibrantly animated videos, which interpret and portray the principal concepts through photographs, easy-to-understand diagrams, and charts. These lessons are a fantastic boost to your visual learning, but if you prefer quickly scanning a written lesson, you can do that too. Each text lesson separates content into sections, highlights key terms in bold, and includes a summary at the end.
1. Taxonomy: Classification and Naming of Living Things
The name you give to a living thing may be completely different than the name someone else uses. In science, we use a common naming system for all living things to avoid confusion. This lesson will explore the basics of our classification system.
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.
3. 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.
4. 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.
5. 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.
