Answer 1

These are 3 common ways of dispersal of seed:

1. Wind Dispersal - Dandelions, swan plants, and cottonwood trees have light seeds with feathery bristles that can be carried long distances by the wind. Some plants, such as kauri and maple trees, have seeds with 'wings.' They flutter to the ground rather than float away. Wind dispersal causes seeds to be blown around and land in a variety of locations. These plants must

produce a large number of seeds in order for at least some of the seeds to land in a suitable location for growth.

2. Water Dispersal - Numerous plants have seeds that disperse through water. The seeds disperse from the parent plant. Mangrove trees can be found in estuaries. A mangrove seed can begin to root in the soil if it falls during low tide. If the seeds drop into the water, the tide will carry them away to grow someplace else. Water dispersal is also used by kwhai trees. They have a tough seed coat that enables them to float down rivers and streams.

3. Animal Dispersal - In New Zealand's woody forests, almost 70% of plants produce fleshy fruit that is devoured by birds. Chemicals in the digestive systems of our native birds help to break the tough coverings that surround these seeds. Birds distribute seeds in their droppings by flying far away from the parent plant. Seed distribution is greatly aided by the kereru and bellbird.

Answer 2

Following are three typical methods of seed dispersal:

1. Wind Dispersal - Light seeds with feathery bristles, like those of dandelions, swan plants, and cottonwood trees, may be transported over great distances by the wind. Seeds from several plants, like kauri and maple trees, feature "wings." They don't float away; they flutter to the earth. Seed dispersal occurs when seeds are dispersed by the wind and settle in various places. In order for at least part of the seeds to fall in an ideal area for development, these plants need to generate a lot of seeds.
2. Water Dispersal - The seeds of many plants are transported by water. From the mother plant, the seeds scatter. Estuaries include mangrove trees. A first mangrove seed  can begin to root in the soil if it falls during low tide. If the seeds drop into the water, the tide will carry them away to grow someplace else. Water dispersal is also used by kwhai trees. They have a tough seed coat that enables them to float down rivers and streams.
3. Animal Dispersal - In New Zealand's woody forests, almost 70% of plants produce fleshy fruit that is devoured by birds. Chemicals in the digestive systems of our native birds help to break the tough coverings that surround these seeds. Birds distribute seeds in their droppings by flying far away from the parent plant.
