1. SUPREME ECOLOGY
Unit 8

2. Population Dynamics Populations change from: Births Deaths Immigration
Emigration

3. Biotic vs. Abiotic Factors
Plants
Animals
Bacteria
Fungi
Protists
Sunlight
Wind
Soil
Moisture
Temperature

4. Carrying Capacity
Number of people, other living organisms, or crops that a region can support without environmental degradation

5. Zones of the Ocean
Intertidal zone—between low and high tide
Neritic zone—from intertidal zone to continental shelf… most biomass
Bathyal (BATH-ee-uhl) zone— from neritic zone to base of continental shelf
Abyssal zone –lies below m
Based off of distance from shoreline and water depths
intertidal zone
neritic zone
bathyal zone
abyssal zone

6. Criteria to Divide Ocean into Zones
Open sea & ocean floor
Presence of light
Distance from shoreline
Water depth

7. Changes to an Ecosystem
Due to:
Seasonal variations
Climate changes
Succession

8. Changes in Biodiversity
Increase
Decrease
What are some benefits? What are some downsides?

9. Trophic Levels 10% Rule Producers get energy from sun
Reduction by 90% at each level
Producers get energy from sun
Primary consumer = herbivore
Secondary consumer = carnivore
Why do trophic levels typically stop at the tertiary or quaternary levels?

10. Food Web vs. Food Chain

11. Biogeochemical Cycles - Water

12. Biogeochemical Cycles - Carbon

13. Human Impact How do humans impact environmental systems? Food
Growing, harvesting, waste/disposal
Technology
Cars, phones, etc
Pollution
Water, air

14. Energy Use Renewable Nonrenewable Solar Wind Geothermal Hydroelectric
Biomass
Impacts?
