Carrying Capacity of Ecosystems
Use mathematical and/or computational representations to support explanations of factors that affect carrying capacity of ecosystems at different scales.

Biodiversity and Populations in Ecosystems
Use mathematical representations to support and revise explanations based on evidence about factors affecting biodiversity and populations in ecosystems of different scales. 

Ecosystem Dynamics, Functioning, and Resilience
Evaluate the claims, evidence, and reasoning that the complex interactions in ecosystems maintain relatively consistent numbers and types of organisms in stable conditions, but changing conditions may result in a new ecosystem.

Social Interactions and Group Behavior
Evaluate the evidence for the role of group behavior on individual and species’ chances to survive and reproduce.

Human Impact on Biodiversity Solution
Create or revise a simulation to test a solution to mitigate adverse impacts of human activity on biodiversity.
