Study Jams! Population Growth
Along came a spider, who sat down beside her. She screamed, but RJ wouldn't smash it because spiders are a limiting factor for other insects in an ecosystem. In this video, other common limiting factors for populations are listed....
Lesson Planet
Populations : Biotic Potential
Why do most populations remain stable over time? Usually it is a result of either environmental resistance or carrying capacity. Examine some of the factors that help stabilize animal populations, and explore some of the changes that...
Lesson Planet
Populations : Distribution
Learn about the different ways in which populations are distributed in a setting. Which animals group together? Why? What are the advantages (or possible disadvantages) to each style of grouping?
