Seed dispersal is the process by which seeds are transported away from the parent plant. There are a number of methods of seed dispersal, including dispersal carried out by both biotic and abiotic means. Among the biotic means, birds and insects carry out seed dispersal. Even human beings do it. Imagine if you are driving and you took an apple along with you. You eat the apple and throw the remainder in the dustbin along the way. Now the seeds have reached a new place and thus have dispersed away from the parent. Among the abiotic means, transport by wind and water are common methods of seed dispersal. For plants near a stream, any fruit or flower that falls down in the water can potentially be carried away to new locations.
There are a number of advantages of seed dispersal, including the colonization of new territories, less competition for resources, and a safeguard against infection and predators, among others.
Hope this helps.
