2.）Hasani is a farmer. He uses a weed killer to control the weed population growth on his farm. Weed killers can stop the transportation of certain minerals in plants through the hair root tissue. Explain why.
How to answer this 2 question. Thanks ​

Answer 1

1) sap is mostly sugar, so an aphid must consume a lot of sap to meet its nutritional requirement for protein.

Insects tend to be most active in the early morning that's why aphids are mostly found in the daytime

2) These herbicides interrupt cell division, which stops root growth in seedling weeds. Plants die because they cannot take up enough water and nutrients to sustain growth.
