Answer:
1) One is natural fiber and another is synthetic or man made fiber. Natural fibers are extracted from plants and animals. Manmade fiber are polyester, rayon, viscose staple fiber. Its is a process of wood pulp chemically treated and processed to make a fiber equal to natural fiber with same qualities.
2) Fiber or fibre is a natural or synthetic substance that is significantly longer than it is wide. ... Yarn is a long continuous length of interlocked fibres, suitable for use in the production of textiles, sewing, crocheting, knitting, weaving, embroidery, or ropemaking.
3) Cotton is a soft, fluffy staple fiber that grows in a boll, or protective case, around the seeds of the cotton plants of the genus Gossypium in the mallow family Malvaceae. The fiber is almost pure cellulose. Under natural conditions, the cotton bolls will increase the dispersal of the seeds.
The plant is a shrub native to tropical and subtropical regions around the world, including the Americas, Africa, Egypt and India. The greatest diversity of wild cotton species is found in Mexico, followed by Australia and Africa. Cotton was independently domesticated in the Old and New Worlds.
The fiber is most often spun into yarn or thread and used to make a soft, breathable textile. The use of cotton for fabric is known to date to prehistoric times; fragments of cotton fabric dated to the fifth millennium BC have been found in the Indus Valley Civilization, as well as fabric remnants dated back to 6000 BC in Peru. Although cultivated since antiquity, it was the invention of the cotton gin that lowered the cost of production that led to its widespread use, and it is the most widely used natural fiber cloth in clothing today.
Current estimates for world production are about 25 million tonnes or 110 million bales annually, accounting for 2.5% of the world's arable land. India is the world's largest producer of cotton. The United States has been the largest exporter for many years. In the United States, cotton is usually measured in bales, which measure approximately 0.48 cubic meters (17 cubic feet) and weigh 226.8 kilograms (500 pounds).
4) Weaving is a method of textile production in which two distinct sets of yarns or threads are interlaced at right angles to form a fabric or cloth. Other methods are knitting, crocheting, felting, and braiding or plaiting. The longitudinal threads are called the warp and the lateral threads are the weft or filling.
5) The stems of harvested plants are bundled and immersed in water for 10 to 15 days. The stems rot (the process is called rotting) and fibres are separated by hand. These fibres are converted into yarns to make fabrics.
6) They donot know to knitt so only.
Hope it helped you :)

1.One is natural fiber and another is synthetic or man made fiber. Natural fibers are extracted from plants and animals. Manmade fiber are polyester, rayon, viscose staple fiber. Its is a process of wood pulp chemically treated and processed to make a fiber equal to natural fiber with same qualitiesNatural fabrics, like merino wool, cotton, cashmere, and silk, are made of fibers that are produced by animals and plants. Synthetic fabrics, like polyester, nylon and acrylic, are "man-made" fibers that are created in laboratories.

6.early men used to cover his body by animal skin since there were no production of clothes at that time . Clothing made of materials such as animal skins and vegetation was initially used by early humans to protect their bodies from the elements.
