Minecraft wheat seeds?

Can I do anything useful with seeds in minecraft. I always trade the wheat with the villagers, then the seeds are left with me. What can I do with them?

You can make bone meal in a composter

You can make arable land and grow wheat.

You could build a chicken farm, or you could just compost it, or you could build an extremely fast wheat farm that gets too spammed with bone mealm

I can automate it with a hopper, right?

Yes, just put a box underneath a hopper under this hopper the composter and under the composter another hopper that puts everything in another box

Yes
