Exercise
Form 3: Decomposers and Energy Recycling
In this engaging exercise, Form 3 students will explore the vital role of decomposers in ecosystems, investigating how these organisms break down organic matter and recycle energy, thus sustaining life on Earth. Through hands-on experiments and interactive discussions, learners will deepen their understanding of nutrient cycles and the interconnectedness of living systems.
