The spikes on these gumballs serve a purpose. They allow the seeds to carried away by animals! The seeds stick to the animals fur and they can be carried far and wide, when they fall off they can create new sweetgum trees.
Bellyache bushes spread by explosive releases of seeds. The seeds can be carried off by water or animals for instance.
Seeds can be dispersed in a number of different ways. They may be carried by wind, water or even by animals.
The development of seeds allowed plants to spread widely and colonize the land. Seeds could be carried in animals' intestines or blown by the wind to create offspring far from the original plant.
Seeds for plants are dispensed in a variety of ways. Fruit-bearing plants dispense their seeds into fruit so animals will spread the seeds far. Some seeds, especially in tall grasses, will attach to fur and clothing to be carried away and replanted, some are carried away in pine cones, others have 'wings' or someway to float away by the wind, an example would be the dandelion.
Animals eat plants and the seeds are not digested. The seeds then get expelled by the animals in their feces.
Animals disperse seeds in various ways that include seeds with barbs that get stuck in their feathers or fur and are carried to new areas. They eat the fruit with the seeds and once through the digestive tract, seeds are dropped in other areas. Another way animals disperse seeds is by burying them for later and not retrieving them so they grow into new plants.
The seeds drop into the water and are carried to places where they might grow. Some seeds drop into the mud immediately around the parent tree.I am not completely sure but it should be waterI am not sure but I think it is dispersed by animals when they eat them
by the wind
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.
Typically, seeds are blown by the wind (corn and dandelions, for example) or by having burrs or stickers that cling to the fur of passing animals. Some seeds are carried by birds, or other animals to new locations.
Most commonly in the lymph nodes. You get the bubonic plague most commonly through infected fleas carried by rats or animals. It is very rare in the united states.
