This resource explores the concept of energy flow within ecosystems and the importance of recycling in conserving energy. It provides an activity where students can model a food web, illustrating the transfer of energy through trophic levels. The document explains the 10% rule, which indicates that only about 10% of energy is passed on to the next level in a food web, with the rest being used for life processes or lost as heat. Additionally, it compares energy transfer in natural systems with energy savings achieved through recycling, particularly aluminum cans, highlighting the significant reduction in energy consumption when recycling. Students engage in reflection, comparative analysis, and model-based explanations to deepen their understanding of energy dynamics in both ecological systems and recycling processes.
