BIOL 212: Introduction to Ecology

The primary focus of ecology is the interaction of organisms with their living and non-living environments.

Organisms, populations, communities, ecosystems, and the biosphere.

Population ecology focuses on the dynamics of a single species' population, while community ecology examines the interactions between multiple populations.
