Question

which of these statements is best supported by the following data? *
experimental plot of wheat crop (4m x 45m) | wavelength (nm) | wave intensity (joules/m²) | crop yield (g/m²)
a | 357.6 | 0 | 110
b | 357.6 | 0 | 110
c | 357.6 | 20 | 30
d | 357.6 | 25 | 20

options:

• wheat plants exposed to high-intensity ultraviolet light produce higher production
• wheat plants exposed to high-intensity ultraviolet light have a lower crop yield
• none of the above

1 point

Explanation:

• For plots A, B, C (wave intensity = 0), crop yield is 110 g/m². For plot D (intensity = 20) yield is 30, plot (intensity = 25) yield is 20. As intensity increases, yield decreases. So high - intensity UV light lowers crop yield.

Answer:

Wheat plants exposed to high - intensity ultraviolet light have a lower crop yield
