How does Maslow’s hierarchy explain human motivation?

"Maslow’s hierarchy describes physiological, safety, belonging, esteem, self-actualization, and self-transcendence needs. The most basic needs generally receive priority, but different levels can influence a person at the same time because human motivation is not strictly separated into steps. Unmet deficiency needs can produce anxiety and tension, while higher needs concern personal potential, meaning, altruism, and spirituality."
