Answer 2

Heya,

Weeds are the unwanted plants which grow in between the crops.

They need to be removed because they affect the crop production.

They make use of all the nutrients required for the crop for being healthy.

The competition for nutrients increases and there are chances of crop failure.

So, they need to be plucked when they are grown in between crops.
