Answer:

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.
