About This Chapter
Interdependent Relationships in Ecosystems - Chapter Summary
When you study this chapter, you'll review video lessons on the interdependent relationships in ecosystems. Some of the topics covered include ecosystems, abiotic factors in an ecosystem and the biotic potential and carrying capacity of a population. Additional lessons discuss the limiting factors of population growth and an overview of populations. Once you complete this chapter, you should be ready to do the following:
- Outline the factors that lead to population density and change
- Discuss interspecific competition, niche differentiation and competitive exclusion
- Define intraspecific competition with an example
- Identify different kinds of symbiotic relationships
- Detail methods of pollination and flower-pollinator relationships
- Explain behavioral ecology and animal behavior
- Describe the cost-benefit of altruism and kin selection
- Provide examples of animal behaviors that aid in reproduction
Study at your own pace and at any time on your computer or mobile device with this flexible and expertly designed chapter. All of our videos are accompanied by multiple-choice quizzes to test your memory. If you need to go back and review any of the subjects, use the video tabs to quickly do so.
1. What Is an Ecosystem? - Definition & Explanation
Similar to a car engine that is made up of multiple parts working together, an ecosystem has interacting parts that support a whole. But how do we define an ecosystem and what are the components they consist of?
2. Abiotic Factors of an Ecosystem: Definition & Examples
When it comes to ecosystems, a mountain, a river, and a cloud have more in common than you might think. Abiotic factors have specific and important roles in nature because they help shape and define ecosystems.
3. Biotic Potential and Carrying Capacity of a Population
When you look around, you can see a number of different individuals and species. In this lesson, we will explore the factors that control and define how many organisms can really inhabit a particular ecosystem or habitat.
4. The Limiting Factors of Population Growth
Is it possible for any one population to grow so large it takes over the planet? In this lesson you will learn the answer to that question. You will learn about the limiting factors of population growth and how it controls population numbers.
5. Populations: Density, Survivorship and Life Histories
Have you ever wondered how biologists determine the populations of animals in a particular geographic area? Watch this video lesson to find out, and discover how scientists look at the survivorship and life histories of many different species.
6. Factors that Lead to Population Change & Density
Can a population keep growing forever and ever? The answer is no. But do you know why that's the case? Here you'll learn the many factors at play in population changes stemming from population density.
7. 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.
8. 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.
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.
10. Methods of Pollination and Flower-Pollinator Relationships
Ever wonder why bees are attracted to specific flowers? We will look at why certain animals are drawn to certain plants and other methods of pollination in this lesson.
11. Behavioral Ecology & Animal Behavior
We all wish we could blame certain behaviors on genetics. Well, maybe we can. In this lesson, explore the study of evolved behavioral traits and discover how these develop in response to ecological pressure, then test your understanding with a brief quiz.
12. Social Behavior: The Cost-Benefit of Altruism and Kin Selection
Ever wonder why people are more likely to help their relatives than complete strangers? Social behavior can help explain this and other actions. Let's look at the cost of certain behaviors.
13. Animal Behaviors that Aid in Reproduction
Reproduction is the fundamental driving force behind animal behavior. Here we will examine some of the behaviors that ensure reproductive success, and you can test yourself at the end with a brief quiz.
