Answer:
Hunting/gathering for Paleolithic, Farming for Neolithic.
Step-by-step explanation:
The Paleolithic era more generally refers to a time in human history when foraging, hunting, and fishing were the primary means of obtaining food. Humans had yet to experiment with domesticating animals and growing plants.
However,
The Neolithic era brought forth the agricultural revolution. During this period, humans began domesticating plants such as wheat, barley, lentils, flax and, eventually, all crops grown in today's society. Neolithic humans also domesticated sheep, cattle, pigs and goats as convenient food sources.
