A. Read pages 118-122 and answer Questions pages 135-136: 1-4, 11, 12. Due 5 December.
Terms & Concepts: Understand the definition of a population and how this differs from the concept of an ecosystemand a biome. Be able to list the four characteristics of a population (geographic distribution, density, growth rate, and age distribution) and be able to give examples. Be sure you understand that density measures the number of individuals in a given amount of area; not necessarily the total number of individuals in the population . Appreciate the factors that determine how fast a population grows in a given unit of time (the growth rate) including birth and dearth rates, and immigration and emigration. Distinguish between an exponential and a logistic growth curve. Appreciate that exponential growth can only take place for a limited amount of time under ideal conditions. Be able to explain why the logistic growth pattern is the typical situation for animals and plants. Understand how changes in the birth and/or death rates determine the shape of the logistic growth curve. Understand the relationship of the carrying capacity to limiting factors in the environment.
B. Questions pages 135-136: 5-6, 13-14, 28. Due 7 December.
C. Read pages 124-128 and answer Questions pages 135-136: 7-8, 15-19. Due 12 December.
Terms & Concepts: Appreciate the role of limiting factors in determining the growth rate and the carrying capacity of a population. Be sure to understand that limiting factors are part of the abiotic and biotic environment and can change over time. Distinguish between density dependent and density independent factors and be able to describe specific examples of each. Read the essay on page 128 as a n example of the role of predators in a population and how politics and human activity can influence this relationship.
D. Questions pages 135-136: 24-25, 29-30. Due 14 December.
E. Read pages 129-132 and answer Questions pages 135-136: 9, 20-23. Due 19 December.
Terms & Concepts: Review the graph of human population growth on page 129. Appreciate the relationship of this graph to important events in human history and their consequences on population growth. Be able to relate this graph to the concepts of an exponential and logistic growth curve. Understand the science of demography studies the relationship of factors such as age, birth, and death rate to human growth. In particular, understand the principle of the demographic transition and its consequences on future population growth. Study the graphs of age structure of the two human populations and what they predict for the future of these two countries.
F. Read the article"Ten Myths of Populations" from Discover Magazine and answer these Questions. Due 4 January.
G. Questions pages 135-136: 26-27, 32. Due 6 January.
