TR 2. Thought Lab 1.1: Analyzing Energy Transfers
Complete Analysis questions 2, 3, and 4 on page 20 of the textbook. Try to do question 4 without
looking at the solution located at the bottom of the page. It is a bit tricky and you will never be asked to
do it again in this course but it demonstrates an important concept that you need to understand to move
forward.
1.About 80% of the world’s population eats mostly grain-based goods. Why do you
think that is the case?
I believe that 80% of the worlds population eats mostly grain based goods because it has a lot of
energy, is easy to grow and inexpensive.
2. How might diet influence the number of humans that Earth can ultimately support?
A diet high in meat takes a larger area to support both factors. Therefore if more people ate their food
directly from the source (grain based diet) there could be more people and the number of humans Earth
can support would increase.
3. One Square meters of land that is planted with rice produces about 5200 KJ of energy
per year. A chicken farm produces 800 KJ/m^2 of potential food energy per year.
Assume that a human must consume 2400 KJ per day to survive. Although it is an
oversimplification to the imply that a person could survive by eating only one type of
food, calculate the total area of land needed to support the student population of your
school for a year on a diet of a() rice and (b) chicken
