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
use graph for the following
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
properties of population
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!
ddlf vs dilf
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
small population
SMALL POPULATION
  • 9. Small populations are more likely to have what two events happen?
  • INBREEDING
  • EXTINCTION
symbiosis
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
limiting factors
LIMITING FACTORS
  • 11. Space, food and mates are 3 types of ____________________ _______________?
  • LIMITING FACTORS!!! ANYTHING THAT LIMITS A POPULATION IS A LIMITING FACTOR.
competition
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
types of succesion
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.
slide11

14. Which type of model shows how the populations have changed over a period of time?

  • DEMOGRAPHIC TRANSITION MODEL
ecological succession
ECOLOGICAL SUCCESSION
  • 15. What is an example of ecological succession?
  • POND CHANGING INTO A MEADOW
predation
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
