Exercise
Cellular Respiration and Ecosystem Energy Flow
In this interactive learning path, students will explore the vital processes of cellular respiration and how energy flows through ecosystems, culminating in a hands-on experiment to illustrate the transformation of energy in living organisms. Engage in stimulating activities and discussions that highlight the interconnectedness of life and the importance of energy transfer in maintaining ecological balance!
