Matter Cycling in Ecosystems

Develop a model to describe the movement of matter among plants, animals, decomposers, and the environment in an ecosystem

How to tell they’ve got it

Tick these off as you see them — no test required.

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

Try this together

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?

Builds on

Ecology Vocabularyages 8–10Modelling movement of matter through ecosystems requires nutrient cycle and decomposer vocabulary

Food Chains & Energy Transferages 8–9Must understand food chains with producers/predators before modelling matter cycling through ecosystem

Biodiversityages 9–11Biodiversity/ecosystems enriched by curriculum matter movement in ecosystems

Ocean Ecosystemsages 9–11Ocean ecosystems parallels curriculum matter movement in ecosystems

Energy from Food & the Sunages 10–11Energy flow from sun through organisms supports understanding matter cycling
