Draw a food chain that includes a producer, and 2-3 animals. Show arrows!
Progress reports ON DESK! 

2. Intro to Ecology and Energy Flow

3. Ecology
Study of interactions of organisms and their environment.

4. Part of planet in which life exists
The Biosphere
Part of planet in which life exists

5. Biosphere Organization
Species: group of organisms that can breed and produce fertile offspring.

6. Biosphere Organization
Population: groups of individuals of same species that live in the same area.

7. Biosphere Organization
Communities: groups of different populations that live together in a certain area.

8. Biosphere Organization
Ecosystem: All the organisms that live in a particular place together with their nonliving environment.

9. Biosphere Organization
Biome: group of ecosystems with same climate and similar plant and animals

10. Methods to Study Ecology
Observing
Experimenting
Modeling

11. FOOD CHAIN
Series of steps in which organisms transfer energy by eating and being eaten.

12. Complex interactions between organisms Multiple food chains!
FOOD WEB
Complex interactions between organisms
Multiple food chains!

13. Each step in a food chain or food web.
Trophic Levels
Each step in a food chain or food web.

14. Bell Ringer 3/8/2013
What is the difference between a food chain and a food web?
Include QUESTION and ANSWER!
Food Chain: Consists of a producer & 2-3 animals
Food Web: Complex & consists of many food chains

15. Shows amounts of energy or matter contained within each trophic level
Energy Pyramid
Shows amounts of energy or matter contained within each trophic level
Bottom: Plants
Top: Tertiary Consumer

16. Energy Pyramid

17. Biological Magnification
Accumulation (build up) of toxins in organisms
GREATER Biological Magnification as you move UP in tropic levels in a food chain
Top of the food chain Most affected

20. Biomagnification

21. Bell Ringer 3/8/2013
What is biological magnification? Which organism is affected the most?
Include QUESTION and ANSWERS!
Accumulation (build up) of toxins in organisms: MORE toxins as you move up the food chain
Top of the food chain Most affected
