Example: What Feedback Looks Like

Student submitted:

A food chain shows how energy moves from one living thing to another. For example, a grasshopper eats grass, then a frog eats the grasshopper, and finally a snake eats the frog. This shows how energy goes from the grass to the snake.

Strengths

  • Clearly identifies the flow of energy
  • Provides a simple example of a food chain

To Improve

  • Could include a decomposer in the chain
  • Could specify the ecosystem the chain belongs to

Tips for Better Food Chains

  • Always start with a producer (plant)
  • Include a decomposer to show the cycle of nutrients
  • Consider the ecosystem when choosing organisms
  • Make sure the arrows show the direction of energy flow
