Plant produces food by converting light energy into chemical energy. The process of food making in the body of plants takes place in the leaves. Hence the leaves are called the food factory of the plant. Digestion is a process in which the organisms in just food and derive energy. The digestion, absorption and assimilation of food is mediated by the digestive system in the body of an individual The undigested food material gets stored in the rectum in the body of an individual. Wool can be characterized as a natural fiber which is derived from the fleece of the sheep. Merino is a type of sheep that bears the finest wool. The degree of hotness of the matter is called temperature. The thermometer is a device that is used to measure the degree of hotness or temperature in the body of an individual or any matter. The mercury is used in the thermometer as an indicator of temperature. The transmission of heat energy is of three types. That are radiation conduction and convection. In convection the heat energy gets transmitted by actual movement of the particles of a medium. The molecules of the medium carry the heat from one place to another place.
