Form 5: The 10 Percent Energy Rule Calculations
In this engaging exercise, Form 5 students will explore the 10 Percent Energy Rule by calculating the energy transfer efficiency in ecological food chains, helping them understand the flow of energy through trophic levels in ecosystems. Through hands-on activities and problem-solving, learners will deepen their grasp of energy dynamics while enhancing their mathematical skills.
