8.2: Energy Flow Through Ecosystems

Topic 8.2 talks about two key components of ecosystems: energy and matter. This lesson will focus on ways energy transfers between organisms through food webs and tropic levels, and the ways matter and nutrients cycle through the environment, focusing on water, carbon, nitrogen, and phosphorus.
