Foundations of Biology modified 6/27/2017 Chapter 5 Review Use the clues and words to help you write the vocabulary terms from the chapter in the blanks. carrying capacity demography limiting factor 1. the scientific study of human population 2. maximum number of individuals of a particular species that a particular environment can support 3. a factor that controls the growth of a population Answer the questions. 4. When resources such as food, water, and space are unlimited, a population will show growth. 5. Complete the concept map using one of the terms below. density-dependent factors density-independent factors are limited by which include Populations 6. What can scientists learn about populations from the science of demography? Use the graphs below to answer Question 7. 7. Which graph represents exponential growth? Circle the correct answer. Graph 1 Graph 2 Disease Foundations of Biology modified 6/27/2017 Taking a Standardized Test Test-Taking Tip: Mark Questions That Require Guessing When you take a test, read each question carefully. If you can answer the question, do so. If you cannot answer a question, and think you will have to guess the answer, mark it. You can return to it later. Read the following question and answer choices. A change in a population from high birth and death rates to low birth and death rates is known as A. logistic growth. B. demography. C. limiting factors. D. demographic transition. Step 1 Answer the question if you can. If you know the answer, circle it. Move on to the next question. Step 2 If you do not know the answer, mark the question. For example, you may not remember the meanings of all the terms listed in the question above. Lightly draw a star to the left of the question. This will help you to quickly find the question again later. Then, move on to the next question. Continue answering or marking questions until you reach the end of a test section. Step 3 Return to marked questions. Eliminate answer choices you know are incorrect. For example, you might remember that demography is the study of human populations. You know that low birth rates probably do not mean growth. So, you can cross out A and B. Guess between the remaining choices. The answer is D. Self-Test Practice what you have learned by answering the following questions. Read each question and the answer choices. If you cannot answer the question, mark it and return to it later. Answer all questions that require guessing last. 1. The maximum number of organisms of a particular species that can be supported by an environment is called A. carrying capacity. B. logistic growth. C. exponential growth. D. population density. 2. A limiting factor that depends on population size is called a A. density-dependent limiting factor. B. density-independent limiting factor. C. predator-prey relationship. D. parasitic relationship. Foundations of Biology modified 6/27/2017 3. The number of individuals per unit area is A. population growth. B. population density. C. demography. D. demographic transition. 4. Which has an S-shaped growth curve? A. dependent growth B. demographic growth C. exponential growth D. logistic growth 5. Which is a density-independent limiting factor? A. drought B. predation C. competition D. parasitism 6. A population’s growth slows or stops following a period of exponential growth. It is experiencing A. demography. B. immigration. C. population density. D. logistic growth. 7. An age-structure diagram can be used to predict population growth. These diagrams are usually in the form of A. bar graphs. B. line graphs. C. pie graphs. D. summary paragraphs. Short-Response Question Answer the following question in two or three sentences. 8. What is a predator-prey relationship? How does this relationship affect population size?
