Final answer:
Nomadic individuals move between temporary settlements based on the seasonal availability of food and other resources.
Step-by-step explanation:
The term that describes individuals who consistently move or migrate between temporary settlements, depending on food availability, is Nomadic. Nomads typically follow a predictable seasonal pattern of movement, often tracking the availability of resources, such as water and grazing areas for their herds, which contrasts with permanent settlement in one location. Such a lifestyle is said to be part of humanity's ancestral heritage, as people have been moving across lands in response to environmental factors and resource distribution since prehistoric times.
