Answer:Physiological needs
Step-by-step explanation:
Physiological needs - are those needs that are crucial for us to survive which can give us energy to pursue other needs. When these needs are met then it motivates us to go on and climb up to ensure we fulfill other needs.
These are biological elements for us to survive i.e shelter,cloths,water,food,air and sleep.
If our physiological needs are not properly met the person can not function in their optimum level.
Fulfilling these needs will then give someone a chance to focus on pursuing and fulfilling other needs.
