Detailed explanation-1: -Seed dispersal prevents competition between the plant and its own seedlings for sunlight, water and minerals. It also enables the plants to invade new habitats for wider distribution.

Detailed explanation-2: -Seeds that are spread far from the parent plant avoid competition with their relatives for resources and have the opportunity to colonize new areas. Both fruits and seeds have a variety of adaptations for different types of dispersal.

Detailed explanation-3: -Dispersal of seeds is very important for the survival of plant species. If plants grow too closely together, they have to compete for light, water and nutrients from the soil. Seed dispersal allows plants to spread out from a wide area and avoid competing with one another for the same resources.

Detailed explanation-4: -Additionally, dispersal can reduce competition for resources and mates, thereby increasing individual fitness. At local scales, dispersal can be reinforced through inclusive fitness benefits by decreasing competition among kin (Hamilton & May 1977).

Detailed explanation-5: -Dispersion or seed dispersal is the movement or transport of seeds away from the parent plant.
