Part of studying living organisms is examining how they interact with their environment and the other living organisms within their environment. Biologists who study the interactions between living things and their environments are called ecologists, and they work in the field of ecology. In this module, you will learn the basic levels of organization from the individual all the way up to the massive biome regions. In addition, you will explore the field of population dynamics, which is the study of how populations change over time. Then, you will examine how energy flows through ecosystems and what happens when there are disturbances to ecosystems. Finally, you will study the ecosystems that surround you in the Commonwealth of Virginia. As a human, make sure to keep in mind how your actions and the actions of other people impact ecosystems as you complete this module.
