Ecosystem Stability

Back to Unit
Essential Question: How do ecosystems remain relatively stable over long periods?
​

Learning Objective: I can use mathematical representations to explain population growth and carrying capacity of a species.
​

Standards addressed: 
HS-LS2-1. Use mathematical and/or computational representations to support explanations of factors that affect carrying capacity of ecosystems at different scales.

HS-LS2-6. 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.
