Use the model to trace matter and energy separately. In this model, solid arrows represent matter movement and dashed arrows represent energy flow. The model includes a producer (corn plant) and consumers (mouse, owl). The model shows that matter and energy follow different paths, so they must be traced separately.
Model (text description):
- Sun →(dashed) Corn plant
- Corn plant →(solid) Mouse
- Mouse →(solid) Owl
- Owl →(solid) Decomposers →(solid) Soil nutrients →(solid) Corn plant
- Corn plant →(dashed) Mouse →(dashed) Owl →(dashed) heat to surroundings
Which choice identifies an error in a student's tracing?
Student tracing: "Energy goes Sun → corn plant → mouse → owl → decomposers → soil nutrients → corn plant."
