Question

Why do seed to be dispersed

Answer 1

Plants make seeds that can grow into new plants, but if the seeds just fall to the ground under the parent plant, they might not get enough sun, water or nutrients from the soil. Because plants cannot walk around and take theirseeds to other places, they have developed other methods to disperse(move) their seeds

Answer 2

Because if the seed will be at only in a certain place then the competition between plants will increase and the there will be race to live more, to get nutrients more and more and only in a single place it is not possible..

And any plant could be die..
