how does a wheat seed "work"? Does it "die" in order to produce other seeds? How does that work?

Answer 1

The seed contains the embryonic plant. It doesn't "die', or nothing else would happen after that. It matures, grows into a young plant and eventually a mature plant, just as an animal embryo doesn't "die', but develops into the mature form.

Answer 2

Any seed (not just wheat), when planted, will "germinate". This means the tiny little proto-plant that is inside every seed will begin to grow. This new little plant first feeds on the seed itself to fuel it's drive to the sun. And roots grow to gather more minerals into the plant. Then when the plant has grown enough to lift it's head above the earth it's growing in, it uses the minerals and water it is collecting with it's roots, and the sunlight it collects on it's leaves, to feed itself and to grow strong and healthy. The plant grows until it becomes mature, and flowers. This is the plants reproductive phase. The flowers will be pollinated by either insects or the wind, and new seeds will begin to grow inside the flower. When these seeds mature and dry, they fall to the ground to begin the cycle again.
