7. Content Energy is necessary for survival
Many forms of energy are not directly usable and must be transformed
First Law of Thermodynamics: we cannot draw more energy from a source than the amount of energy that is stored in that source
Different foods and fuels contain different amounts of energy

8. Content
Not only is the source of energy important but access to the energy is of huge importance – It must be accounted for in the total energy budget
Second Law of Thermodynamics: thermal energy (heat) is always transferred from areas of higher energy to areas of lower energy

9. Content
To get the most energy from a food supply, we need to obtain the food in edible form with minimum energy expenditure.
What are the characteristics of such sources?

10. Chapter 1 Energy Population Assessment ?? Would you recommend
the use of nuts for food,
fuel, or both? Cite evidence
from your work that supports
your choice and explain why you
choose one over the other. Write
your answer in your notebook.
