What four factors affet population change?
Write an equation showing how population change is related to births, deaths, immigration, and emigration.
What is the biotic potential of a population? Whare are four characteristics of a non-human population with a high intrinsic rate of increase (r)?
What are environmental resistance and carrying capacity? How do biotic potential and environmental resistance determine the carrying capacity? List four factors that can alter an areas carrying capacity for animals.
Distinguish between exponential and logistic models for growth of a population? Why is this important relative to carrying capacity?
What happens if a population overshoots its carrying capacity? What are potential consequences?
Clearly describe the difference between population growth rate and population size.
Describe how different age structures can lead to different population growth rates even with the same population size (Figure 11-16).
Describe the difference between optimal sustainable yield, maximum sustainable yield, carrying capacity and cultural carrying capacity.
Describe the stages in the demographic transition (Figure 11-26). What are the four stages? What factors might keep many developing countries from completing this demographic transition?
What are the cultural changes that can lead to decreases in the birth rate?
List five reasons why the world's death rate has dropped over the last 100 years.
What are the three main systems that supply our food? What three single crops provide most of the world's food?
Distinguish between industrialized, plantation, traditional subsistence and tranditional intensive forms of agriculture.
What is a green revolution? What three steps does it involve? Distinguish between the first and second green revolutions.
Distinguish between undernutrition, malnutrition, and overnutrition. What are the most common nutritional deficiencies?
About how many chronically malnourished people are there in the world? What are six ways to reduce sickness and death from malnutrition.
List the major harmful environmental effects of producing food.
What is sustainable agriculture? Why is it important?
