1. Beginning in 1950, global agricultural production increased dramatically due to technical
innovations and improvements collectively referred to as the first and second green
revolutions. Which of the following are part of the green revolutions? Check all that
apply.
a. Heavy equipment use
b. Pesticides
c. High water use for irrigation
d. Multiple cropping
e. Polyculture
Question2:
Which of the following decreased during the first green revolution? Check all that apply.
-The amount of human labor necessary to grow 1 acre of corn
-The amount of nitrogen and phosphorus applied to 1 acre of corn
-The amount of corn grown on 1 acre of land
-The amount of pesticide applied to 1 acre of corn
-The energy expended in irrigating 1 acre of corn
Question3:
Plot a grann to anaivze the relationsnio between the dramatic changes in phosphorus Induts and corn vields In the
vears represented in the preceding
table
Herers now For eacn or ne vears in tne tadie, Diace a data point on ine graon sucn rnat tne norizontal position
represents poungs or pnosnorus anc
the vertical position represents bushels of corn. The first ear has been plotted as an example with a blue circle. In
1940, the average acre of corn
received 7 pounds of phosphorus and produced 34 bushels of corn. The blue circle's coordinates are 7, 34). That Is,
it is 7 units along the horizonte
axis and 34 units along the vertical axis. Notice that the vear itself, 1940, is not graphed at all.)

2. To plot the remaining five vears data. click on the orange sauare labeled "Data"' to the right of the arach and drag it to
the desired position on the
graph. Repeat until all data points are represented
Question4:
if corn yeilds had changed at exactly the same rate as phosphorus inputs did then all of the data points would lie on
the slope reference instead, the data points are below it, which of the following are valid interpretations.
-corn yields decreased more rapidly than phosphorus in.
-Phosphorus inputs increased more quickly than corn yields.
-Phosphorus inputs increased more slowly than Corn yeilds.
-By the end of the first green revolution, the average bushel of corn required more phosphorus than it did a 1940.
