Answer:
1 - Weeding is a vital process for an active collection because it ensures the collection stays current, relevant, and in good condition. Weeding should be done on a continuous, on-going basis.
2- Rabi crops are sown at the end of monsoon or the beginning of winter. They are also known as winter crops. Kharif crops are sown at the beginning of the rainy season and are also known as monsoon crops.
3 - Food preservation slows down the activity of disease-causing bacteria or kills bacteria in food altogether. Preserving food keeps it from spoiling too quickly and allows it to last for weeks or even months.
4- Answer (a) It is necessary to dry the harvested food grains before storage because the grains contain the moisture contents. The moisture content in the grains promotes the growth of fungus and moulds in the grains. (b) The two ways in which farmers store food grains are in jute bags and in metal bins at home. 32.
