Q1
Use the model to trace matter and energy separately. In this model, solid arrows show matter movement and dashed arrows show energy flow. The model includes a producer (seaweed) and consumers (urchin, sea otter). The model shows that matter and energy follow different paths, so they must be traced separately.
Model (text description):
- Matter (solid): Seaweed → Urchin → Sea otter → Decomposers → Ocean nutrients → Seaweed
- Energy (dashed): Sun → Seaweed → Urchin → Sea otter → heat to water/air
Which claim is incorrect according to the model?
