Title: Energy Transfer & Loss: Trophic Levels & Energy Pyramids Summary: In this interactive lab, students explore how energy moves through ecosystems using cloze notes, 10% energy calculations, and hands-on energy pyramid modeling. Students learn why energy decreases at each trophic level, why food chains are short, and how movement, respiration, and body heat reduce energy availability. The activity includes math practice, pyramid construction for various ecosystems, reflection questions,
