About This Chapter
Community Ecology Overview - Chapter Summary
The lessons in this chapter provide an overview of community ecology. You can review competitive exclusion and niche differentiation with these engaging text and video lessons. Our expert instructors also explain how different animals require a different balance of water and solutes for survival. After completing the chapter, you should be prepared to:
- Define and provide an example of intraspecific competition
- Explain potential outcomes of interspecific competition
- Describe how predator/prey interactions can influence appearance for some animals
- Recall the beginning and end stages of ecological succession
- Discuss three common types of plant adaptations
- Recount challenges to osmoregulation
Each lesson comes with a brief quiz to ascertain how much of the content you can recall. You can study all the lessons for a more comprehensive review or focus only the topics you need to review. Use your personal Dashboard to keep track of the lessons you've completed and your quiz results.
1. Intraspecific Competition: Example & Definition
How do members of the same species share resources? There's an ongoing struggle among individuals of the same species called intraspecific competition, and this competition is one way that nature controls how large a population gets.
2. Interspecific Competition, Competitive Exclusion & Niche Differentiation
What happens when two similar species that consume the same resources occupy the same space? Interspecific competition, that's what! Watch our video lesson to learn about the outcomes of this ecological battle.
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. 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.
5. Plant Adaptations: Hydrophytes, Mesophytes & Xerophytes
In this lesson, you'll learn about plant adaptations. You'll also learn about three of the most common types of plant adaptations: hydrophytes, mesophytes, and xerophytes.
6. Osmoregulation: Definition, Challenges & Energetics
Cells need a certain balance of water and solutes to survive, but this balance is different for different animals. Just as different is how animals regulate this balance, which you'll learn about in this video lesson.
