-There are many ways of dispersal.

-Without dispersal,seeds will crowd at an area and it would be figthing over water and sunlight.

Interesting facts about seed dispersal

Elephants eat the fruits that have fallen from the trees and deposit the seeds in their droppings several miles away.Dispersal is to spread the seeds away from the parent plant to prevent overcrowding.

Sea beans

It is dry and grows in a pod.

Water Dispersal

Coconut

Has a fibrous husk that traps air allowing the seed the float on water

seeds dispersed by animals often has a fruit which contains a seed in it. Plants such as burdock have hooks to which the seed is attached. These hooks easily get caught in the fur of mammals as they pass by the plant.

Explosive

As a pod dries, tensions are set up in the wall of the pod eventually causing it to split along two lines of weakness.

As the two halves curl back, suddenly released like a tense spring, they flick out the seeds inside in an explosive manner.
