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

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

I understand the concept of carrying capacity and how limiting factors influence this, and use quantitative analysis to determine the carrying capacity

I can identify limiting factors and can tell the specific factors that limit a given habitat, quantitatively I cannot tell the carrying capacity without errors.

I can identify limiting factors and can tell the specific factors that limit a given habitat, quantitatively I can tell the carrying capacity with errors.

Given a scenario, I can identify the limiting factors that set the carrying capacity of a given area and can quantitatively determine the carrying capacity with little errors.

Given a scenario, I can identify the limiting factors that set the carrying capacity of a given area and can quantitatively determine the carrying capacity with no errors.




I can explain the concepts of biodiversity and population dynamics using data, graphs, and figures.

I can identify what biodiversity is and explain population dynamics, but cannot use data, graphs and figures.

I can identify what biodiversity is and explain population dynamics, and use data, graphs and figures with errors.

Given data, I can compare different habitats on the basis of biodiversity and population dynamics with little errors.

Standard 4B Populations & Limiting Factors

I understand the concept of carrying capacity and how limiting factors influence this, and use quantitative analysis to determine the carrying capacity

  • I can identify and define the difference between interspecific and intraspecific competition.

  • I can explain how limiting factors create a carrying capacity

  • I can identify if a limiting factor is density-dependent or density independent.

  • I can differentiate between an S curve (logistical) and an J curve (exponential)

  • I can use data to determine the carrying capacity for a given area and draw a dotted line to indicate it.

I can explain the concepts of biodiversity and population dynamics using data, graphs, and figures.

  • I can find an average number of individuals in a given population

  • I can identify trends in population data over time

  • I can explain the concept of biodiversity using graphs and figures.

  • I can compare two habitats and explain which has more biodiversity based on given data, graphs and figures.
