Answer:
The three different ways are mentioned as under:
1) Wind dispersal
2) Dispersal by water
3) Dispersal by animals
Step-by-step explanation:
1) Wind dispersal: Wind dispersal is very common mode of seed transfer from one plant to another plant. Seeds of some plants are light in weight. Therefore, they can be easily blown away from one plant at a particular region to another region which is distantly located. Some examples of such plants are kauri, maple trees etc.
2) Water dispersal: The seeds of some plants are dispersed by water. In this way of dispersal, the seeds are blown away by flowing water. This mode of seed dispersal is not very common. The seeds of vallisneria, sea grass etc. are dispersed by water.
3) Dispersal by animals : Seeds can be dispersed by animals too. When animals pluck the fruits from a plant and eat the fruit, the seed of that fruit enters their digestive tract. When those animals excrete, that time the seed comes out of their digestive tract and grow as an independent plant. Some animals pluck the fruit and eat the pulp and throw the seed at far away place from the tree. That seed then grows as an independent tree at a distantly located area. Examples are : Mango tree, raspberry etc.
