Final answer:
Agriculture involves the practice of growing crops and raising livestock, which can include both intensive agriculture and pastoralism, depending on the techniques used and the focus of the activity.
Step-by-step explanation:
The practice of growing crops and raising livestock is commonly referred to as agriculture. This involves the cultivation of the soil to grow crops and the rearing of animals to provide food, raw materials, and other products to humans. The term also encompasses various agricultural techniques such as intensive agriculture, which focuses on growing a small number of crops, often grains or legumes, to generate surplus for trade.
Meanwhile, practices like pastoralism involve the nomadic herding of animals, moving frequently in search of grazing pasture, and can also form part of an agricultural way of life. Different forms of agriculture require different levels of labor, investment, and can range from subsistence farming to commercial agriculture.
