Ecology and the Biosphere
The Scope of Ecology
Introduction to Ecology
Ecology is the study of organisms, populations, and communities as they relate to one another and interact in the ecosystems they comprise.
Organismal Ecology and Population Ecology
Organismal and population ecology study the adaptations that allow organisms to live in a habitat and organisms' relationships to one another.
Community Ecology and Ecosystem Ecology
Community ecology studies interactions between different species; abiotic and biotic factors affect these on an ecosystem level.
