In his will he leaves you $15 million to invest in a small shopping center, but to get the $ 15 million you need to move to his small town, which was mostly destroyed by a tornado and invest all of your new money into businesses in the town. You are approached by many companies to open businesses. You can open 5 businesses for your center. Pick 5 and explain why you made your combination of business is the best to make money. Your choices are:

2. UNIT 10: Ecology 1 INTRO TO ECOLOGY pp. 359-365

3. Ecology Defined Ecology means "study of homes" study the relationships of animals, plants, and their environment (interdependence) A small change can affect the whole ecosystem

5. Levels of Organization

6. Biosphere : Most Inclusive + all below Ecosystem + abiotic factors Community: all organisms + many populations Population: members of one species in one place + many organisms = Organism : Least Inclusive

8. Niche/Habitat Niche - the job/role of an organism in their environment (usually based on what they eat) 1. generalist: broad niche 2. specialist: narrow niche 3. specialist more at risk from habitat destruction than generalists 4. some times two organisms have the same niche- competition

9. Habitat 1. geographic location 2. habitats overlap 3. some organisms are territorial - defend habitat

10. Ecology of Organisms Response to biotic (living) and abiotic (nonliving) factors 1. acclimation: adjust tolerance 2. conformers vs regulators 3. dormancy vs migration 4. limited resources

11. Dealing with the Ecosystem Control of Internal Conditions (2 ways) Conformer: organisms that do not control their internal conditions they conform to the environment – cold blooded Regulator: organisms that control their internal conditions (regulate despite the environment – warm blooded)

12. Dealing with the Ecosystem Escaping Unsuitable Conditions – Dormancy: hide and reduce activity for the duration of the conditions (ex/ bear hibernates for the winter) – Migration: relocate away from the conditions. (ex/ birds fly south for the winter)

13. ENERGY TRANSFER pp 366-369

14. In an ecosystem energy flows: Sun  autotrophs  heterotrophs producers consumer

15. PRODUCERS Can make their own food through photosynthesis or chemosynthesis Productivity: energy made by producers (after biological processes) available to consumers

16. gross primary productivity: rate at which producers capture energy in organic compounds. (Carbs, Fats, Proteins) biomass: the amount of organic material produced net primary productivity: the rate at which biomass accumulates (after some is used)

17. CONSUMERS get energy by eating other organisms - herbivores: eat producers - carnivores: eat other consumers - omnivores: eat producers and consumers - detritivores: feed on “garbage” - decomposers: breakdown big molecules to smaller molecules and recycle materials

18. ENERGY TRANSFER trophic level: position in a series of energy transfers

19. Only 10% of the total energy is passed onto the next trophic level 1. lost to biological processes 2. lost as heat 3. not enough at level above to support below
