Exercise
Decomposers and Organic Material Recycling
In this engaging exercise, students will explore the vital role of decomposers in ecosystems by investigating how these organisms break down organic materials, recycle nutrients, and contribute to soil health, using hands-on experiments and observations to connect theory with real-world ecological processes.
