List 3 ways species can disperse.

These are wind, water, animals.

wind - some plants e.g. Eurasian dandelion  produce seeds that  resemble parachutes. The seeds  have an elevated umbrella-like crown of intricately branched hairs at the top.  The slightest gust of wind catches the elaborate plumose  hairs, raising and propelling the seed into the air like a parachute.   

Water - plants such as the willow and silver birch trees which  grow beside water produces small light seeds that are carried by water to other places.

Animals - plants such as the black jack produce fruit or individual seeds covered in hooks or spines which attach to the fur or feathers of animals or in the case of humans, to our clothes. The seeds are then carried to a sufficient distance away from the parent plant.
