Answers
Answer:
Animal Husbandary: Food is also obtained from animals for which animals are reared and provided with proper food, shelter and care. When done on a large scale, it is called animal husbandry.
Harvesting and Threshing: When crops pet matured, they usually turn yellow or golden or brown. This is the time when crops should be cut. Cutting of crops is known as harvesting. Harvesting is either done manually by a sickle or by a machine called harvester. Harvested crop is further dried and then animals such as bullocks, buffaloes, camels are made to walk over it. The grains are separated from chaff with the help of wind (winnowing). The whole process of separation of the grains from the harvested crop is known as threshing.
Big farmers use huge machines known as combines which do both harvesting and threshing.
Storage: Grains obtained by threshing are dried in the open. The dried grains are stored in gunny bags, and placed in properly ventilated cemented halls, known as godowns. Farmers keep dried grains in jute bags or metallic bins or mud bins. Large scale storage of grains is done in silos and granaries . For storing large quantities of grains in big godowns, specific chemical treatments are used to protect them from pests and microorganisms.
