Worked Solution & Example Answer:The bar chart shows the percentage decrease in yield of four crops as a result of the effects of weeds, fungi and insect pests - Scottish Highers Biology - Question 20 - 2019
Step 1
Predict which crop will show the greatest increase in yield if herbicides and insecticides are applied.
Answer
To determine which crop will show the greatest increase in yield after applying herbicides and insecticides, we analyze the bar chart. Crop D has the highest total decrease in yield due to the combined effects of weeds, fungi, and insect pests. When herbicides and insecticides are applied, we can expect a significant recovery in the yield of this crop.
Therefore, Crop D will demonstrate the greatest increase in yield when herbicides and insecticides are utilized.
