About This Chapter
Interactions Among Living Things - Chapter Summary
Review how living things impact one another and the environments in which they live as you work through our Interactions Among Living Things chapter. Take a closer look at genetic manipulation of plants and animals, evolutionary processes, the difference between a food chain and a food web, and the types of organisms that cause disease. You will learn about the following in this chapter:
- Explanation, definition and varieties of infectious agents
- Introduction to genetics and its applications
- Changes in populations, adaptation and the role of natural selection
- Overview of ecology, ecosystems and the environment
- How energy flows through an ecosystem
- Types and impact of pollution
This powerful study guide offers much more than valuable information. It also contains built-in lesson quizzes and chapter tests so that you have a means to test your knowledge of the material. Specialists in each subject area provide an additional source of information or clarification, and our instructors are ready to answer your questions whenever the need arises.
1. Infectious Agents: Definition & Types
Infectious agents are tricky little invaders. They sneak in, use your body, and often make you sick in the process. In this lesson, you will learn about the different types as well as some common examples of each.
2. Genetics: Heredity, Traits & Chromosomes
We view manipulation of genes in our crops and livestock as a recent development. Yet, man has been manipulating the genetic makeup of his food for thousands of years through cultivation and breeding. This lesson will begin to help you understand how genetics works.
3. Natural Selection & Adaptation Processes
Through the process of adaptation, natural selection shapes the variety of life that exists around us. This lesson will explore some of the ways this process can take place.
4. Theories of Evolution: Lamarck vs. Darwin
We'll look at the interplay between population genetics and environment. Are traits individually acquired or do entire populations evolve? The flying hamsters and a few other notable experiments will provide the answers.
5. 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.
6. 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.
7. Pollution: Physical, Chemical & Biological
Pollution is the presence of unwanted substances in an environment. It is often the result of human interference. Learn about physical, chemical and biological pollutants and see examples of each.
