These seeds must get to a place so that they can start to make a new tree. Trees have four ways to spread their seeds. This process is known as seed dispersal The first form of seed dispersal is wind. Some trees produce seeds that can use the wind to carry it away from the parent tree to a suitable place for it to grow. The second form of seed dispersal is animals.
Animals can help spread seeds in several ways.
In some trees the seed is in the middle of a fruit. When an animal eats the fruit it cannot digest the seed and the seed is expelled when it goes to the bathroom. Some animals bury the seeds to store them, like when you store food in the refrigerator. Some of these seeds do not get eaten and sprout into new trees. Animals with fur can also help trees disperse their seeds.
