Example: What Feedback Looks Like
Student submitted:

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
