3.  Habitat  Biotic factor  Abiotic factor

4.  Population  Community  Ecosystem  Ecology

5.  Food, water, shelter  Things to live, grow, and reproduce

6.  Environment where organism lives  With your Pair Share partner, describe the habitat of a prairie dog or sunfish, you choose!  Include three things that allow the organism to live, grow, or reproduce

7.  Biotic and Abiotic

9.  Organism, population, community, ecosystem

12.  Fill in the parts of the ecosystem: OrganismPopulationCommunityEcosystem Honey beeForest

13.  Name the biotic factors in the ecosystem.

14.  Name the abiotic factors in the ecosystem.

15. Living Things and the Environment worksheet due at the end of the hour!

16.  Limiting factor  Carrying capacity

18.  Organisms leave or die, populations smaller  Organisms join or are born, populations larger

19. Climatep. 15 Space limits growth Food Water

20.  What four things limit population size?

21.  Populations graphing due at the end of the hour!

23.  Natural selection  Adaptation  Niche  Competition  Predation

24.  Adaptations = traits that an organism had to eat, grow, or reproduce  Some are better than others!

25. BEHAVIORS  Migrate v. stay in environment  Strong sense of smell v weak sense of smell PHYSICAL TRAITS  Long tongue v short tongue  Bright wings v dull wings  Wide span wings v short wings

27.  Natural process  The strongest adaptations will allow for survival  The weaker adaptations will result in death!

28.  Which butterfly will naturally be more likely to survive and reproduce?  Why?

29. Natural selection assumes that the weaker traits or behaviors will cause a part of a species to die out!

32.  Competition – struggle for limited resources  Niche – animals “job”

33.  Predator hunts, eats prey

34.  Symbiosis  Mutualism  Commensalism  Parasitism
