2. What do organisms need to survive and reproduce?
Outline for organisms
Introduction
What do organisms need to survive
and reproduce?
How do organisms cope with variability?

3. Niche: ecological role of a species in the community
- determines the range of conditions an organism can tolerate, how it feeds, how it escapes enemies, etc.
- no two species have the same niche

4. Habitat: the physical setting in which an
organism lives

5. What do organisms need to survive and reproduce?

6. Fig. 9.4

7. How do organisms cope with variability?
behavioral adaptations
physiological adaptations
developmental adaptations

8. behavioral - organisms can alter their behavior to stay within range of environmental conditions required to survive and reproduce

9. preferred temp.

11. physiological - the physiology of an organism can change such that the range of environmental conditions it can tolerate changes
- reversible
- acclimation

12. Figure 9.9

13. Figure 9.10
blue = grown at 20 C orange = grown at 40 C

14. How do organisms cope with variability?
behavioral adaptations
physiological adaptations
developmental adaptations

15. developmental - particular traits of an organism may be affected by the environmental conditions under which it develops
- irreversible

17. Surviving extreme conditions
For example, long, cold winters or long, very dry seasons

18. Introduction and review of adaptation

example of variability
in food resources

19. optimal foraging theory – organisms will forage in a way that maximizes energy intake per time while minimizing risk
In lab – had to forage in way that maximized bean capture and minimized getting tagged by predator

20. Figure 9.16

21. Do starlings forage optimally?
Figure 9.18

22. Should an organism risk predation to forage in an area with a lot of food?
