Question

1. base your answer on the information and graph below and on your knowledge of biology. an unusually cool and wet spring prevented certain farmers from planting corn at the usual time. they normally planted their crop on may 1, but the altered weather patterns delayed planting until june 1. corn yield as affected by planting date graph description: x - axis is planting date with values 5 - apr, 15 - apr, 25 - apr, 5 - may, 15 - may, 25 - may, 4 - jun, 14 - jun; y - axis is % of max yield with values from 50 - 110 based on the information given, what is the most likely impact of the delayed planting on the production of corn? a) corn yield will remain at 100% because higher temperatures in june will make plants grow faster. b) the corn yield may be reduced by about 20% because of the delay in planting. c) corn yield may be reduced by about 80% because of the delayed planting. d) crops planted on june 1 will have the same yield as those planted on april 1.

Explanation:

Examine the graph which shows the relationship between planting date and corn yield. The normal planting date was May 1 but it was delayed to June 1. Looking at the graph, the yield percentage for June 1 is around 80% of the maximum yield, indicating a reduction from the optimal yield when planted earlier. So, a delay in planting is likely to reduce the yield by about 20% compared to the maximum possible yield.

Answer:

B. The corn yield may be reduced by about 20% because of the delay in planting.
