Check understanding
- Describe the role of decomposers (fungi, bacteria, worms) in breaking down dead matter
- Trace the movement of matter: plant grows using soil nutrients → animal eats plant → animal dies → decomposers return nutrients to soil
- Create or interpret a simple diagram showing matter cycling through an ecosystem
“Can your child explain what happens to a fallen leaf on the forest floor — how tiny organisms break it down and the nutrients go back into the soil to help new plants grow?”
