Form 7: Energy Pyramids and Biomass

In this engaging exercise, students will explore the concepts of energy pyramids and biomass by creating their own models to illustrate energy flow through different ecosystems, enhancing their understanding of food chains and ecological balance. Through hands-on activities and critical thinking questions, learners will discover the importance of energy transfer and biomass in supporting diverse life forms.
