because
1.for avoiding over crowding
2.to eliminate in competitons
3.so that seeds can grow in other places that need plants
4.for the continuation of plants and species life
seeds dispersed by animals
eg. tigernail seeds ,etc.
tigernail seeds have hooks which help it to be dispersed by animals
so it cannot be dispersed by wind......
if it is wrong i am sorry.
all the plants' seeds would fall in one place . There would be no space for all of the seeds to germinate and grow . All of them will die in the end.
Ripe fruits of Impatiens when touched burst suddenly. The fruit valves roll inwards and the seeds ejected with great force and get dispersed in all directions.
Seeds of all cultivated plants are dispersed by mammals including human being. Seeds of edible fruits are also dispersed by wild animals, like monkeys and squirrels.
No, in fact some seeds lay dormant for many years and others are triggered by heat (only germinate after a forest fire).

Seeds are dispersed in fruits to help spread them across a large area. Apples, Oranges, and plums all use this ability reduce over population and provide the best change of success for future generations.
Tomato seeds are the obvious example. A visit to a sewage purification works in Summer will show you young tomato plants growing all over.

Sheeps are one, they catch seeds, I forgot what they are called but-...now I remember, dandelions, as their (sheeps) fur scrape against the dandelions their seeds get hold onto it, until sometime it falls of and that's how it gets dispersed. That's all I know sheeps are a disperser as well as dogs although they do the same thing as sheeps (using their fur, as the seeds fall of by their selfs).
it cant because of...wind and its all gas.
All fruits have seeds, as that is the point of having fruit (the seeds get eaten by animals then dispersed throughout after passing through the animal's digestive tract). The only fruit that don't have seeds are the ones that humans have selectively bred not to produce seeds.
