Answer 1

We don’t plant every seed. We scatter grass seed and there are/were some flower mixes that worked the same way. But there are thousands of seeds we’re scattering and we don’t care that much about the positions. We plant them because we care that they grow in rows to make harvesting easier or a plethora of other reasons we want specific placement. We plant seeds because we’re trying to optimize the output be it flowers , fruits or vegetables. And if we don’t plant them birds will eat them.
