# S4L1: Ecosystem Roles and Energy Flow

Obtain, evaluate, and communicate information about the roles of organisms and the flow of energy within an ecosystem.

- Subject: Science
- Appears in: Grade 4, https://georgiahomeroom.org/standards/science/grade-4.md

## Expectations

- **S4L1.a**: Develop a model to describe the roles of producers, consumers, and decomposers in a community.
- **S4L1.b**: Develop simple models to illustrate the flow of energy through a food web/food chain beginning with sunlight and including producers, consumers, and decomposers.
- **S4L1.c**: Design a scenario to demonstrate the effect of a change on an ecosystem.
- **S4L1.d**: Use printed and digital data to develop a model illustrating and describing changes to the flow of energy in an ecosystem when plants or animals become scarce, extinct or over-abundant.
