# SEN1: Insect Roles in Ecosystems

Obtain, evaluate, and communicate information about the roles of insects in ecosystems.

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

## Expectations

- **SEN1.a**: Construct an explanation for the role(s) of insects in diverse terrestrial and freshwater food webs (i.e., as herbivores, predators, and scavengers) and the need for conservation.
- **SEN1.b**: Ask questions to compare and contrast the prevalence of specific insect species in local Georgia regions.
- **SEN1.c**: Use mathematics and computational thinking to compare species diversity and biomass in different terrestrial habitats and evaluate why insects dominate both measures in most regions (e.g., field plot population sampling).
- **SEN1.d**: Construct an explanation of the importance of insects in ecosystem sustainability (e.g., plant pollination, decomposers/recyclers of organic matter).
- **SEN1.e**: Plan and carry out an investigation to demonstrate how some groups of insects are used as bio-indicators because they are sensitive or tolerant to habitat change conditions.
- **SEN1.f**: Construct an argument based on evidence to demonstrate co-evolution/co-adaptation relationships between various insects and plants (e.g. pollination syndrome).
