# SEV2: Ecosystem Stability and Change

Obtain, evaluate, and communicate information to construct explanations of stability and change in Earth's ecosystems.

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

## Expectations

- **SEV2.a**: Analyze and interpret data related to short-term and long-term natural cyclic fluctuations associated with climate change.
- **SEV2.b**: Analyze and interpret data to determine how changes in atmospheric chemistry (carbon dioxide and methane) impact the greenhouse effect.
- **SEV2.c**: Construct an argument to predict changes in biomass, biodiversity, and complexity within ecosystems, in terms of ecological succession.
- **SEV2.d**: Construct an argument to support a claim about the value of biodiversity in ecosystem resilience including keystone, invasive, native, endemic, indicator, and endangered species.
