All living organisms require food in order to obtain energy for body development and survival. Agriculture and animal husbandry provide us with food from both plants and animals. It is critical to improve food resources in order to meet the population's ever-increasing demand. To achieve this, we need sustainable agricultural and animal husbandry practices that do not jeopardise the environment or natural balance. Sustainable and scientific management practices include mixed farming, intercropping, and integrated farming. Join this class to learn in detail about improvement in food resources.

Aishwarya Ma’am will also share with you a few important questions from this chapter to help you be better prepared to take any questions from this chapter.
