Here are different way seeds can be dispersed..
1.) After the seeds have formed, they are usually scattered, sometimes far from where they were produced. The scattering of the seeds is called "seed dispersal".
2.) Water. Water can disperse seeds that fall into oceans and rivers.
3.) Wind. Wind disperses lightweight seeds that often have structures to catch the wind.
4.) Some plants eject their seeds, and the force scatters the seeds in many directions.
5.) When seeds are mature, the scales open. The wind shakes the seeds out of the cone and carries them away. Only a few seeds will land in suitable places and grow into new plants.
6.) Fruits are the means by which angiosperm seeds are dispersed. Animals that eat fruits help to disperse their seeds.
=======================
By wind - most grasses use this way;
by animals - most plants with brightly coloured flowers and edible fruits; and
by water - e.g. coconut
=======================
The 3 means of seed dispersal are the wind, theres also the birds and other critters eating the fruit or nut and then defecating the seeds in another spot. Also water carrying the seeds from the plant they originated from to another spot.
=======================
Seed can be dispersed in various manners; this is normally dependant on the physical characteristics of the seed or seed coat or the fruit containing the seed.
Seed dispersal is necessary to move plants to new locations, this reduces overpopulation and competition for resources in the same location, dispersal also extends the physical range of the plants into new ecological regions. Indirectly it improves the chances of the new plants being able to interbreed or improve the gene pool of the particular plant, plants grown in very isolated or specific closed regions have very little genetic diversity and are cannot cope with sudden threats to their existence.
The agents or mechanisms of dispersal are also known as vectors of dispersal.
Animals: Seed contained in edible fruit (e.g. figs, tomato, mango, berries) can be distributed by animals which eat the fruit and then eventually excrete them in another location. Examples: Bats, monkeys, squirrels, cattle, wild herbivores.
Insects: Many insects collect seed for food (ants, termites etc.), the seed is then taken back to the nest where it may germinate or be dropped and germinate.
Wind: Certain seed is adapted to dispersal by wind; these normally have a wing or similar appendage that allows the seed to be carried by air currents. Examples, pine seeds (wing), Acer seed (wing), Maple and Dandelion.
Gravity: Certain seeds are heavy and rounded in shape, this facilitates the seed falling from the seed pod and rolling a distance from the parent plant.
Burrs and hooks: Certain seeds have burrs, hooks or thorns, the aim of these is to attach themselves to the skin or fur of a passing or foraging animals (or clothes in the case of humans); the animal then moves to another location where hopefully the seed drops and germinates. Examples include: Burdock and Foxtail.
Mechanical/ Explosive dispersal: Some plants have "exploding" pods that physically throw the seed away from the parent plant. Examples of these include: Impatiens/ Balsam and some legumes.
Water: Some seeds, particularly of plants that grow close to the coast or rivers are adapted to float in order to be distributed away from the parent. Most water plants employ this method of dispersal. Examples are Coconuts, mangrove plants and Lotus.
Fire: While fire per se is not a method of dispersal it is a key factor in releasing seed (or breaking seed dormancy) of some species that otherwise would not be able to be released or germinate. Examples include Protea, Erica, certain Pines and some Banksia species.
Once you know what the shape and characteristics of the seed are, you can use the above information to determine how the seed is most likely dispersed. Cherry has a stone and a fruit sweet fruit covering, so it is most likely dispersed by animals, birds, bats or even gravity.
=======================
Gravity , where the seed drops to the ground -
wind , where the seed is spread by air-born forces (Think of a Dandelion seed.) -
water , which can carry the seed downstream - animal , where the seed can be carried in fur or through animal droppings -
humans , where the seed can be spread through planting ~ the related link below will provide more information regarding seed dispersal .
=======================
1.Disperse seeds by water.
2.Disperse seeds by wind.
3.Dispersal by animals.
4.Some plants eject their seeds.
=======================
1. Wind dispersal: dandelions have fruits with parachutes of hairs that catch the wind and are blown about. Sycamore fruits have wings which can be blown about and carried over distances.
2. Water dispersal: fruits which float, such as those of the water lily and the coconut palm are carried by water. Coconuts can travel for thousands of kilometres across seas and oceans. The original coconut palms on South Sea islands grew from fruits which were carried there from the mainland by ocean currents. Mangroves in swamp regions in countries such as Thailand are another example.
3. Animal dispersal: seeds of juicy fruits are carried by birds and other animals. The fruits are eaten, but only the juicy parts are digested, but only the juicy parts are digested. The stones and pips leave the animal's body via the droppings which may be some distance away from the parent plants. e.g. blackberry, cherry and apple. In the case of mistletoe, the sticky fruits are eaten by birds which then clean their beaks on the bark of trees, leaving behind a sticky seed which can grow into a new mistletoe plant on the tree. (Mistletoe is a plant parasite). Small seeds can be carried on the feet of birds and other animals. Fruits with hooks and barbs, e.g. the burdock fruit are carried in the hair, fur and wool of animals. Squirrels bury nuts, including acorns, for food supplies over the winter, but sometimes leave some behind which may grow into new plants in the spring.
4. Explosions: some plants disperse their own seeds. The pods dry and split open suddenly with some considerable force which throws their seeds for some distance. e.g. laburnum, broom, peas.
=======================
Seeds can be dispersed using
- wind;
- animal vectors such as birds which disperse the seeds in their droppings, or animals that disperse the seeds by transporting them stuck to their fur;
- explosive seed pods. Some seeds are exploded from a ripe seed pod;
Well, it would be more helpful if you could be more specific as seeds can be dispersed in many more ways than one! There is wind, where the seeds if light enough are carried away be it. Animals could eat the seeds and disperse of it else where in it's dung.
Seeds can be dispersed through various mechanisms such as wind (anemochory), water (hydrochory), animals (zoochory), and self-dispersal mechanisms like explosion and gravity. Each method helps the seeds reach new environments for germination and growth.
Seeds can be dispersed by wind, water, insects, birds, mammals and by self splitting of fruits
Air (wind), water, in the guts of animals, stuck to the outside of animals (including insects).

What are two ways a seeds moved?
Seeds can be dispersed by animals, which eat the seeds and then spread them through their droppings. They can also be dispersed by wind, where the light seeds are carried away by the breeze to new locations.
How are mimosa seeds dispersed?
Mimosa seeds are dispersed primarily through pod dehiscence, where the pods dry out and split open, releasing the seeds. The seeds may also be dispersed by animals that eat the pods and then excrete the seeds elsewhere. Additionally, mimosa seeds can be carried by wind or water to new locations.
How are lightweight seeds dispersed?
Lightweight seeds can be dispersed by wind, water, and animals. Wind-dispersed seeds usually have adaptations like small size and wing-like structures. Water-dispersed seeds can float and travel long distances before being deposited. Animals may eat the seeds and then disperse them through their droppings.
How are seeds despersed?
Seeds are dispersed in various ways, such as by wind, water, animals, or through explosion. Wind-dispersed seeds are lightweight and have structures like wings or hairs to catch the wind. Some seeds can float in water, aiding in dispersal across bodies of water. Animals may eat seeds and then deposit them in a different location through their droppings, helping the seeds to grow in new areas. Finally, some plants have pods that explode, propelling the seeds away from the parent plant.
How are hickory nut seeds dispersed?
Hickory nut seeds are primarily dispersed by animals like squirrels, who bury them for storage and then forget about them, allowing the seeds to germinate. Other methods of dispersal include wind and water, which can carry the seeds to new locations.
