WebThe scattering of seeds or fruits is known as dispersal. There are two reasons for seeds to be dispersed: To prevent overcrowding. Dispersal ensures that the young plants grow far apart from each other. This reduces competition between the young plants and/or with the parent plant for sunlight, water, nutrients and space.
