The cards describe the relationships between different organisms in the food web.
-Use the relationships AND the scribble tool to draw arrows showing how matter moves through the ecosystem.
-Your arrow should point in the direction that matter moves.
-Let's do the raccoon together as an example.

Each set of cubes represents the body matter of the organism.

The cubes for represent food/body matter (molecules) for each organism (living thing)
What was happening to the molecules in the ecosystem as the cubes (the matter) were getting passed from one organism to the next?

The Food Web Model can help us think about how matter flows when something in the ecosystem changes.
