Plants have limited mobility and rely upon a variety of dispersal vectors to transport their propagules, including both abiotic vectors such as the wind and living vectors like birds. The seeds in the above example latched onto your pants to disperse, but they may also catch on the fur of animals. Seed dispersal is the movement or transport of seeds away from the parent plant. If all seeds of a plant fall under the parent plant they will grow crowded together and many will die because of lack of space or air, water, sunlight and minerals.
