# SEV1: Ecosystem Energy and Matter Flow

Obtain, evaluate, and communicate information to investigate the flow of energy and cycling of matter within an ecosystem.

- Subject: Science
- Appears in: High School, https://georgiahomeroom.org/standards/science/high-school.md

## Expectations

- **SEV1.a**: Develop and use a model to compare and analyze the levels of biological organization including organisms, populations, communities, ecosystems, and biosphere.
- **SEV1.b**: Develop and use a model based on the Laws of Thermodynamics to predict energy transfers throughout an ecosystem (food chains, food webs, and trophic levels).
- **SEV1.c**: Analyze and interpret data to construct an argument of the necessity of biogeochemical cycles (hydrologic, nitrogen, phosphorus, oxygen, and carbon) to support a sustainable ecosystem.
- **SEV1.d**: Evaluate claims, evidence, and reasoning of the relationship between the physical factors (e.g., insolation, proximity to coastline, topography) and organismal adaptations within terrestrial biomes.
- **SEV1.e**: Plan and carry out an investigation of how chemical and physical properties impact aquatic biomes in Georgia.
