How Do Seeds Spread?

Seeds spread through the help of people, animals, wind and water. Some plants eject their seeds from their seedpods. One way in which seed dispersal occurs is when a seed gets caught in an animal's fur or a bird's feathers.

When animals travel to other areas, they inadvertently transport seeds. Animals also help spread seeds by consuming fruit that has seeds. When animals excrete their waste, seeds end up in other locations. Wind also helps transport small seeds that have structures to help them fly. Water sources, such as rivers and creeks, move seeds, regardless of their size. For example, coconut can be easily transported via water.
