HS-LS2-1 Ecosystems: Interactions, Energy, & Dynamics 

Students who demonstrate understanding can: Use mathematical and/or computational representations to support explanations of factors that affect carrying capacity of ecosystems at different scales. 
Clarification Statement: Emphasis is on quantitative analysis and comparison of the relationships among interdependent factors including boundaries, resources, climate and competition. Examples of mathematical comparisons could include graphs, charts, histograms, or population changes gathered from simulations or historical data sets. 
Assessment Boundary: Assessment does not include deriving mathematical equations to make comparisons.

Science & Engineering Practices 

Disciplinary Core Ideas 

Scale, Proportion, and Quantity:

  • The significance of a phenomenon is dependent on the scale, proportion, and quantity at which it occurs. 

Using Mathematics and Computational Thinking:

  • Mathematical and computational thinking at the 9–12 level builds on K–8 and progresses to using algebraic thinking and analysis, a range of linear and nonlinear functions including trigonometric functions, exponentials and logarithms, and computational tools for statistical analysis to analyze, represent, and model data. Simple computational simulations are created and used based on mathematical models of basic assumptions. 
  • Use mathematical and/or computational representations of phenomena or design solutions to support explanations.  

Interdependent Relationships in Ecosystems:

  • Ecosystems have carrying capacities, which are limits to the numbers of organisms and populations they can support. These limits result from such factors as the availability of living and nonliving resources and from such challenges such as predation, competition, and disease.
  • Organisms would have the capacity to produce populations of great size were it not for the fact that environments and resources are finite. This fundamental tension affects the abundance (number of individuals) of species in any given ecosystem.
