1. The Biosphere – Chapter 3
How are nutrients important in living systems. Explain how matter moves among living and nonliving parts of an ecosystem.
2. Explain how energy flows through living systems and how efficient is the transfer of energy among organisms.
3. Explain the different levels of organization ecologists study

2. What is Ecology?
The interactions of organisms with one another and with their physical surroundings

3. That part of the Earth in which life exists
Biosphere
That part of the Earth in which life exists

4. Levels of organization
Species: group of organisms that Breed and produce fertile offspring

5. Populations
Key:
Group of individuals that belong to the same species and live in the same area.

6. Organisms living together in an ecosystem
Community
Organisms living together in an ecosystem

7. Ecosystem Physical features Abiotic factors = physical features
water sunlight, soil type rocks, temp.
Biotic Factors = living organisms
shark, fish, coral, tube worms, arthropods

8. Biome
Key:
Group of ecosystems that have the same climate and similar dominant communities.

9. Tundra Locations: Northern North America, Asia and Europe
Characteristics:
Treeless biome
Covered in mosses, lichens and grasses
Animals migrate in summer to feed on plants
Carnivores follow the food migrating
Permafrost = Permanently frozen subsoil

12. Ecological Methods Keys: - Observing
* Collecting data to make an educated guess (hypothesis)
- Experimenting
* testing changes in natural ecosystems
- Modeling
* models help predict what could happen ecologically over a long period of time. (Global Warming)

13. Energy Flow Keys: Main source of energy? The Sun Autotrophs
Energy from the environment to fuel the production of simple into complex organic compounds
Producers?
Make their own food

14. Energy From the Sun Keys: Photosynthesis
Use solar energy to convert CO2 and H2O into O2 and C6H1206

15. Life Without Light Keys: Chemosynthesis
Use chemical energy to convert CO2 and H2O into chemical compound and C6H1206
Life Without Light

16. Consumers Keys: Acquire energy from other organisms Heterotrophs
Five types:
Herbivores: Cows / Deer
Plant eaters
Carnivores: Snakes / owls
Animal eaters
Omnivores: Bears / crows
Best of Both worlds
Detritivores: Mites / earthworms
Plant and animal remains
Decomposers: Bacteria / fungi
Break down organic Matter

17. Food Chain
Keys:
Transfer of energy by eating and being eaten

18. The Food Web
Keys:
Feeding Relationships among organisms

19. Trophic Levels Keys: Each step of the food chain or food Web.
Each consumer depends on the trophic level below for energy.

20. Ecological Pyramids Keys:
Diagram in your notes the following Ecological Pyramids.
Three Types
Energy Pyramid
Biomass Pyramid
Pyramid of Numbers
Be able to define each pyramid
Relate the pyramids to the different trophic levels.

21. Nutrient Cycles Keys: NUTRIENTS
Substances organisms need to sustain life.
Build tissues and carry our life functions
Biogeochemical cycles
Passed between organisms and the environment
