Final answer:
Livestock is used on resource-poor farms through practices such as pastoralism and ranching. Pastoralism involves nomadic herding of animals, while ranching involves raising animals for meat production. Livestock farming is important for the livelihoods and food security of people in resource-poor areas.
Step-by-step explanation:
Livestock is utilized on resource-poor farms through practices such as pastoralism and ranching. In areas where crop agriculture is not feasible due to limited rainfall, cold temperatures, or hilly terrain, livestock production becomes the primary agricultural activity. Pastoralism involves nomadic herding of animals like cattle, sheep, and reindeer, where herds are moved frequently to find grazing pastureland. Ranching, on the other hand, involves raising animals for meat production in regions where more profitable agricultural land uses are not possible. Livestock farming plays a vital role in the livelihoods and food security of people in resource-poor areas, especially in developing nations.
