1. Food: Stone Age humans met this need by hunting, gathering, and fishing. They would hunt for meat, gather fruits and vegetables, and fish for seafood.
2. Water: Stone Age humans met this need by finding sources of water, such as rivers, lakes, and streams. They would also collect rainwater in containers.
3. Shelter: Stone Age humans met this need by building shelters from natural materials, such as branches, leaves, and rocks. They would also build caves or find caves to live in.
In addition to these three basic needs, Stone Age humans also had other needs, such as the need for clothing, fire, and tools. They would meet these needs by using the materials that were available to them in the environment. For example, they would make clothing from animal skins, build fires using wood and stones, and make tools from rocks and bones.
