2. Titles for Today: L80: Biosphere R80: Impacts on Biosphere L81: Invasive Species R81: Invasive Species L82: Wanted Poster: Invasive Species R82: Bell Ringers

3. Biosphere L80: Biosphere Biosphere: All life on Earth Atmosphere LithosphereHydrosphere

4. L80: Biosphere Quick Write: (question and answer) How can human activities impact the biosphere?

5. R80: Impacts on Biosphere -Hunting/Gathering (we gain food for ourselves and wipe out entire species and kill animals) -Agriculture (important for food production -caused problems with erosion/pollution and has domesticated animals) -Industrial Growth & Development (coal and oil but pollutes environment and depletes natural resources)

6. R80: Impacts on Biosphere Increasing Population (greater need for food, water and land) Habitat Destruction (deforestation and land development) Introduction of Invasive Species (non-native and can cause harm)

7. L81: Invasive Species An invasive species is: 1) non-native (alien) to the ecosystem 2) whose introduction causes or is likely to cause economical or environmental harm or harm to human health They can be PLANTS, ANIMALS or OTHER ORGANISMS (microbes)

8. L81: Invasive Species -Human actions are the PRIMARY cause for invasive species introductions. Characteristics: -Fast growth -Rapid reproduction -Ability to adapts to certain conditions -Tolerance to wide environmental conditions (weather) -Ability to live off a wide range of food -Out competes native species

9. R81: Invasive Species Once established they are VERY HARD to control their spread! Examples: Kudzu Red Fox Black Rat Gypsy Moth Fire Ant Tree of Heaven Atlantic Salmon

10. R81: Invasive Species

11. These habitats don’t have predators and parasites that can control theses new species…. SO they increase rapidly!
