Decribe the various ways by which seeds are dispersed
Answers
People plant some seeds, but most plants don't rely on people. Plants rely on animals and wind and water to help scatter theirAnimals disperse seeds in several ways. First, some plants, like the burr at left, have barbs or other structures that get tangled in animal fur or feathers, and are then carried to new sites. Other plants produce their seeds inside fleshy fruits that then get eaten be an animal. AcornsThe fruit is digested by the animal, but the seeds pass through the digestive tract, and are dropped in other locations. Some animals bury seeds, like squirrels with acorns, to save for later, but may not return to get the seed. It can grow into a new plant.
Wind dispersal
The kind of seeds which are often wind dispersed are smaller seeds that have wings or other hair-like or feather-like structures. Plants that produce wind blown seeds, like the dandelion often produce lots of seeds to ensure that some of the seeds are blown to areas where the seeds can germinate seeds.Many aquatic plants and plants that live near water have seeds that can float, and are carried by water. Plants living along streams and rivers have seeds that float downstream, and therefore become germinate at new sites. The size of the seed is not a factor in determining whether or not a seed can float. Some very large seeds, like coconuts, can float. Some small seeds also float.
And some plants disperse their seeds in other ways...
Some plants have unique ways to disperse their seeds. Several kinds of plants "shoot" seeds out of pods.
Here is our your answer...
Dispersion refers to the transfer of seeds from one place to another so that they could grow in a proper place and do not compete for nutrition.
Seeds can be dispersed in different ways....
Dispersion by wind---IN THIS DISPERSION THE SEEDS GETS DISPERSED BY THE ACTION OF WIND .FOR EXAMPLE----COTTON.
Dispersion by Water----IN THIS TYPE THE WATER HELPS IN THE DISPERSION.FOR EXAMPLE---COCONUT.
Dispersion by Birds or Insects---IN THIS THE INSECTS AND BIRDS HELP IN THE DISPERSION.FOR EXAMPLE---BERRIES.
Dispersion by explosion---IN THIS TYPE OF DISPERSION THE SEEDS GETS SCATTERED IN THE GROUND BY THE BURSTING OF THE FRUIT.FOR EXAMPLE--PEAS.
