Scientists sowed sorghum seeds in four similar plots. They sowed a different number of seeds in each plot. They allowed the crops to grow to maturity. They then recorded the number of weed plants in each plot. The results are shown in the graph. 30- 45- Number of woods perm² 40- 35- 30- 25 30000 50000 70000 90000 Sowing density of sorghum/ seeds per hectare. 8 (a) (i) Describe the effect of sowing density on the number of weeds per m².
