  1. REVIEW CH 19 and 20

  2. 1. List the types of dispersion of population as pictured above. • a. RANDOM • b. UNIFORM • c. CLUMPED • 2. Which type of dispersion is located at regular intervals? • UNIFORM

  3. USE GRAPH FOR THE FOLLOWING: • 3. Define carrying capacity then identify which section on the graph represents carrying capacity. • Carrying capacity is the maximum number of individuals the environment can support. B. • 4. Which part of the graph represents exponential growth? • A---- look for the “J” shape • 5. Of the 3 parts of the graph, decide whether the population: grew, shrank, or stayed the same in the period of time. • A. grew, b. stayed the same, c. shrank

  4. PROPERTIES OF POPULATION • 6. Why is age structure important if you were going to study a population? What would it tell you about the future of that population? • It tells you the various ages of the population and you can use this to help predict the pattern of population growth. A population that has a lot of individuals in child bearing age is much more likely to increase! • Also remember the other properties of population: size, density, and dispersion!

  5. DDLF VS. DIlf • 7. Competition and disease are two types of what? • DENSITY DEPENDENT LIMITING FACTORS • 8. Weather and natural disasters such as floods and fires are types of what? • DENSITY INDEPENDENT LIMITING FACTORS

  6. SMALL POPULATION • 9. Small populations are more likely to have what two events happen? • INBREEDING • EXTINCTION

  7. SYMBIOSIS • 10. List the 3 types of symbiotic relationships and define each. • PARASITISM- ONE IS HARMED THE OTHER ONE IS HELPED. • COMMENSALISM- ONE IS HELPED THE OTHER ONE IS NOT AFFECTED • MUTUALISM- BOTH BENEFIT

  8. LIMITING FACTORS • 11. Space, food and mates are 3 types of ____________________ _______________? • LIMITING FACTORS!!! ANYTHING THAT LIMITS A POPULATION IS A LIMITING FACTOR.

  9. COMPETITION • 12. What is the difference between intraspecific competition and interspecific competition? • INTRASPECIFIC- 2 OF THE SAME SPECIES COMPETING OVER A RESOURCE • INTERSPECIFIC- 2 DIFFERENT SPECIES COMPETING OVER A RESOURCE

  10. TYPES OF SUCCESION • 13. Explain the difference between primary and secondary succession. • PRIMARY SUCCESSION- IS THE GROWTH OF A COMMUNITY STARTING FROM SCRATCH. NO SOIL INITIALLY. NEVER BEEN ESTABLISHED BEFORE. • SECONDARY SUCCESSION- REGROWTH OF AN AREA, SOIL PRESENT, WAS ONCE ESTABLISHED THEN A DISTURBANCE HAPPENED SO IT HAD TO START OVER.

  11. 14. Which type of model shows how the populations have changed over a period of time? • DEMOGRAPHIC TRANSITION MODEL

  12. ECOLOGICAL SUCCESSION • 15. What is an example of ecological succession? • POND CHANGING INTO A MEADOW

  13. PREDATION • 16. List 2 predator and prey adaptations. • PREDATOR- VENOM, SHARP TEETH, SPEED, SENSE OF SMELL • PREY- MIMICRY, CAMOFLAUGE, FLEE, POISONOUS • 17. Define mimicry and give an example. • One species resembles another. • KING SNAKE AND THE CORAL SNAKE
