2. Day 75 1.3 Extracting Energy From Biomass

3. What does cellular respiration produce?

4. Is it in the presence of oxygen (aerobic condition)? Fermentation occurs when oxygen is absent (anaerobic condition). Organisms like bacteria and some fungi release the energy in glucose.

5. Greenhouse gases

6. Greenhouse gases are atmospheric gases that prevent heat from leaving the atmosphere

7. Reducing Carbon Dioxide in the Atmosphere Initiative 1) Initiative 2) Initiative 3)

8. Reducing Carbon Dioxide in the Atmosphere Initiative 1) Kyoto Protocol – 180 countries signed document to reduce greenhouse gas emissions Initiative 2) Initiative 3)

9. Reducing Carbon Dioxide in the Atmosphere Initiative 1) Kyoto Protocol – 180 countries signed document to reduce greenhouse gas emissions Initiative 2) 2008, Ontario will protect half of its forests (225000 km^2) Initiative 3)

10. Reducing Carbon Dioxide in the Atmosphere Initiative 1) Kyoto Protocol – 180 countries signed document to reduce greenhouse gas emissions Initiative 2) 2008, Ontario will protect half of its forests (225000 km^2) Initiative 3) Recycling helps reduce CO2 emissions

11. Is waste all waste?

12. Waste from Fuel There is no oxygen in a landfill ecosystem. But the bacteria there break down the glucose in the waste using the process of _____________

13. Waste from Fuel There is no oxygen in a landfill ecosystem. But the bacteria there break down the glucose in the waste using the process of _____________ Methane gas is released and that is a fuel!

14. Waste from Fuel There is no oxygen in a landfill ecosystem. But the bacteria there break down the glucose in the waste using the process of _____________ Methane gas is released and that is a fuel! It produced 1.6 MW (megawatts) of electricity per year in Sudbury, Ontario

15. Acid Precipitation Fossil fuels being burned by humans can release undesirable chemicals

16. Acid Precipitation Fossil fuels being burned by humans can release undesirable chemicals Rain, snow, or fog that is unnaturally acidic due to gases in the atmosphere that react with water to form acids  acid rain
