Unravel the complex interactions of organisms with their environments.
Population Ecology, Community Ecology, and Ethology
Population Ecology, Community Ecology, and Ethology
Population and community ecology comprise the interactions between organisms and their environment. Population ecology examines how and why populations—groups of individuals of a single species—change over time, while community ecology focuses on the interactions between species which determine community structure.

Climates, Biomes, and Ecological Restoration
Ecology is the scientific study of the interactions between organisms and the environment. These interactions may be organized into a hierarchy, which we'll discuss in this detailed handout. Note: if you have read the USESO Guide, a lot of content overlaps between Earth science and this topic.
