Symbiosis refers to a long period interaction between two different species. In some cases, both species benefit from the interaction and this becomes mutualism. The larger organism is considered a host because, in a symbiotic relationship, it is the larger organism upon or inside of which the smaller organism lives. The smaller organism is considered to be a symbiont, that lives in or on the host.
Parasitism is the type of symbiotic relationship or long-term relationship between any two species either plants or animals. Here the parasite gains benefits by the host which in turn causing harm without killing the host organism.

From fibres to wool:
To obtain wool sheep are reared. Their hair is cut and processed into wool. Sheep are herbivores and prefer grass and leaves. They also eat mixture of pulses, corn, jowar, oil cakes and minerals. In winters sheep are kept indoors and fed on leaves grain and dry fodder.
Processing fibres into wool:
The wool which is used for knitting sweaters and weaving shawls involves following steps:
- Shearing: The process of removing hair from the body of a sheep in the form of fleece is called shearing. Usually the hairs are removed during the hot weather which enables sheep to survive without their protective coat of hair. The hair provides woolen fibres and than are processed to obtain woolen yarn. Shearing does not hurt the sheep as the upper most layer of skin is dead.
- Scouring: The process of washing the fleece that removes dust, dirt, dried sweat and grease is called scouring. This process makes the fleece of sheep clean. The scoured fleece is then dried.
- Sorting: The process of separating the fleece of a sheep into sections according to the quality of woolen fibres is called sorting. The hairy skin is sent to a factory where hair of different textures is sorted. The same quality wool obtained from the fleece of large number of sheep is than mixed together.
- Dyeing: The hair of sheep is white, brown, or black in color. The white woolen fibres obtained by sorting can be dyed in different colors.
- Combing: This is a process of preparing woolen fibres for spinning the yarn. It is done by using combs having metal teeth.
- Spinning: The long woolen fibres are spun into thick yarn called wool.

| Stomach | |
| The human digestive system has a single stomach. | Ruminants have a complex stomach with four different compartments. |
| Cellulase | |
| Humans do not contain cellulose. | Ruminants contain cellulase that digests cellulose. |
| Bolus | |
| In humans, the bolus is once swallowed it completes the digestion of containing food particles. | In ruminants, when the food bolus is swallowed, it could be coughed up again for further mechanical digestion. |

A greenhouse (also called a glasshouse, or, if with sufficient heating, a hothouse) is a structure with walls and roof made chiefly of transparent material, such as glass, in which plants requiring regulated climatic conditions are grown.[1] These structures range in size from small sheds to industrial-sized buildings. The glass greenhouses are filled with equipment including screening installations, heating, cooling, lighting, and may be controlled by a computer to optimize conditions for plant growth.
