There is a decrease in death rate followed by an increase in birthrate C. There is an increase in death rate followed by a decrease in birthrate D. There is an increase in death rate followed by an increase in birthrate E. There is a decrease in death rate followed by a decrease in birthrate Blooms Level: 4. Analyze Learning Outcome: 36.08.02 Contrast the population growth and age distribution of the more-developed and the less-developed countries. Mader - Chapter 36 #43 Section: 36.08 Topic: Ecology 44. Which of the following statements is not true? A. Currently, over one-quarter of the human population live in LDCs B. The growth rate for MDCs has now stabilized C. The growth rate for LDCs is still growing D. People in LDCs are often underfed and live in poverty E. The LDCs are not fully industrialized Blooms Level: 5. Evaluate Learning Outcome: 36.08.02 Contrast the population growth and age distribution of the more-developed and the less-developed countries. Mader - Chapter 36 #44 Section: 36.08 Topic: Ecology 45. If a population has more younger woman entering the reproductive years than older women leaving the reproductive years, which of the following statements is not true? A. It is likely to be an LDC B. The replacement reproduction will give a positive growth rate C. It is likely to be an MDC D. The age structure will have a pyramid shape E. The growth rate will most likely increase Blooms Level: 4. Analyze Learning Outcome: 36.08.02 Contrast the population growth and age distribution of the more-developed and the less-developed countries. Mader - Chapter 36 #45 Section: 36.08 Topic: Ecology 46. Replacement reproduction occurs because more older women are leaving the reproductive years than younger women are entering. FALSE Blooms Level: 2. Understand Learning Outcome: 36.08.02 Contrast the population growth and age distribution of the more-developed and the less-developed countries. Mader - Chapter 36 #46 Section: 36.08 Topic: Ecology 47. The term for life styles that permit a balance between human needs and preserving the environment is: A. Sustainability B. Ruralization C. Zero population growth D. Environmentalism E. Conservation ecology Sustainability occurs when future generations are able to enjoy the same quality of life as the present generation. Blooms Level: 1. Remember Learning Outcome: 36.08.02 Contrast the population growth and age distribution of the more-developed and the less-developed countries. Mader - Chapter 36 #47 Section: 36.08 Topic: Ecology 48. Which of the following statements accurately describes the less developed countries? A. High birthrate, large postreproductive portion of the population B. High birthrate, different age groups of equal size C. High birthrate, large prereproductive portion of the population D. Low birthrate, large reproductive portion of the population E. Low growth rate, different age groups of equal size Currently, the LDCs are experiencing a population momentum because they have more women entering the reproductive years than older women leaving them. Blooms Level: 4. Analyze Learning Outcome: 36.08.02 Contrast the population growth and age distribution of the more-developed and the less-developed countries.
