Skills
  • identify (factors that may alter carrying capacity) #dok1
  • describe (how specific factors impact carrying capacity) #dok2

Learning Targets
  • I can identify factors such as disease, natural disaster, and available resources that may alter carrying capacity. #dok1
  • I can describe how each factor affects the carrying capacity of a population. #dok2
  • I can explain why carrying capacity is not fixed and depends on changing environmental factors. #dok2
  • I can analyze scenarios to determine the effects of various factors on population and ecosystem stability. #dok3
  • I can predict possible population outcomes when carrying capacity changes due to specific factors. #dok3
Big Ideas
  • Carrying capacity is influenced by both biotic and abiotic factors, which can change over time due to natural or human-caused events.
  • Understanding what alters carrying capacity helps us predict and manage changes in populations and the health of ecosystems.
Essential Questions
  • What is carrying capacity, and why does it change?
  • How do different factors like disease or habitat fragmentation affect the carrying capacity of a population?
  • What role do available food, water, and space play in determining carrying capacity?
  • How can natural disasters or periodic weather changes impact populations and ecosystems?
  • Why is it important for environmental scientists to understand the factors that alter carrying capacity?
