(Figure: Crop Yield and Fertilizer) The graph shows a hypothetical relationship between tons of fertilizer used and crop yields. Which statement is NOT correct?
A) The slope of the curve between 1 and 2 tons of fertilizer is approximately 2.
B) The relationship between fertilizer usage and yield is nonlinear.
C) Because the relationship is nonlinear, it is difficult to create an economic model describing the relationship between the two variables.
D) Using more than 3 tons of fertilizer has minimal effect on yield.
