Presentation Transcript


Use graph for the following
USE GRAPH FOR THE FOLLOWING: above.

  • 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 above.

  • 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. above.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 above.

  • 9. Small populations are more likely to have what two events happen?

  • INBREEDING

  • EXTINCTION


Symbiosis
SYMBIOSIS above.

  • 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 above.

  • 11. Space, food and mates are 3 types of ____________________ _______________?

  • LIMITING FACTORS!!! ANYTHING THAT LIMITS A POPULATION IS A LIMITING FACTOR.


Competition
COMPETITION above.

  • 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 above.

  • 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.



Ecological succession
ECOLOGICAL SUCCESSION changed over a

  • 15. What is an example of ecological succession?

  • POND CHANGING INTO A MEADOW


Predation
PREDATION changed over a

  • 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
