Final answer:
The correct order of needs in Maslow's pyramid is basic needs, safety, love and belongingness, esteem, and self-actualization, with self-transcendence possibly above self-actualization.
Step-by-step explanation:
The sequence that best expresses the order in which the needs in Maslow's hierarchy must be fulfilled, from the first to the last, is: basic needs, safety, love and belongingness, esteem, and self-actualization. This corresponds to the physiological needs (food, water, shelter) at the base of the pyramid, followed by safety needs, social needs (love and belongingness), esteem needs, and finally, at the peak, self-actualization, which is the realization of one's full potential. It is also important to note that later in his life, Maslow introduced the idea of self-transcendence as a level above self-actualization.
