Seed dispersal is essential for plants as it improves the chances of the seeds being able to grow to the adult stage.
Predators target areas which have a high concentration of seeds as they have to spend a lesser amount of time and energy. By dispersing their seeds plants ensure that the number of seeds available for predators to eat right below the parent plant is lesser.
Also, a small plant that grows under the parent plant is denied access to sunlight and nutrients in the right amount. Seed dispersal is an attempt to find better conditions for the plants to grow. Seed dispersal is also a means of colonization of new regions which may not have been inhabited by the plant earlier and which offer good conditions for growth and development.
Answer:
Seed distribution is essential for the survival of a plant species.
Overcrowding forces plants to compete with one another for soil nutrients, water, and light. Plants can disperse over a large region and avoid competing with one another for the same resources by dispersing their seeds.
Seed dispersal can be beneficial in three ways:
(1) escaping density- or distance-dependent seed and seedling mortality;
(2) colonising suitable places that are erratic in space and time; and
(3) directing dispersal to specific sites with a high likelihood of survival.
The ecosystem that plants and animals live in greatly benefits from seed distribution. Reduced overcrowding avoids resource rivalry by reducing competition between the parent plant and its seeds.
