Section 14.4 Population Growth Patterns Page 414 Name ____________________ Vocabulary Immigration Emigration Exponential growth Logistic growth Carrying capacity Population crash Limiting factor Density dependent limiting factor Density independent limiting factor Key Concept Questions 1) What conditions might allow a population to grow? 2) What conditions might cause a population to decrease in size? 3) What 4 factors affect the size of a population? 4) What determines the rate of growth for a population? 5) Draw an exponential growth curve and explain what is happening to the population. 6) Draw a logistic growth curve and explain what is happening to the population. 7) Explain why the actual size of a population is usually higher or lower than the carrying capacity. 8) What might cause a population to crash? 9) List three examples of density dependent limiting factors. 10) Explain what the following sentence means: “A prey population depends upon its predators as much as their predators depend upon them.” 11) Draw a simple predator-prey graph. 12) List 3 examples of density independent limiting factors. 13) A population of algae in a pond is limited in size by the amount of sunlight that reaches the pond. Is sunlight a density dependent or density independent limiting factor for the algae population?
