Practice questions

1 of 28Practice questions for this set
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?​
