GED® Science: Ecosystems & Energy Flow (Deep Dive)

A deep dive into how living things interact and how energy moves through nature, expanding the single 'Ecosystems & Energy Flow' lesson from the GED® Life Science course into a full mini-course. You'll learn the living and nonliving parts of ecosystems, trace energy through food chains and webs, see why energy shrinks at each step (the 10% rule), follow how matter cycles through the carbon cycle, explore population limits and carrying capacity, and study the relationships and disruptions that shape ecosystems. Plain language, all-new labeled diagrams, common-misconception warnings, and GED®-style practice with full explanations throughout.
