Final answer:
Maslow's hierarchy of needs contains five levels starting from the basic physiological needs and progressing to self-actualization.
Step-by-step explanation:
Maslow's hierarchy of needs contains five levels, in ascending order:
- Physiological needs: These include the basic necessities for survival, such as food, water, and shelter.
 - Safety needs: This level involves the need for security, stability, and protection.
 - Love and belongingness needs: This level focuses on the need for friendship, intimacy, and a sense of connection with others.
 - Esteem needs: This level includes the need for recognition, respect, and a positive self-image.
 - Self-actualization: At the top of the hierarchy is the need for self-actualization, which is the fulfillment of one's full potential.
 
Maslow suggested that these needs must be fulfilled in order, with lower-level needs taking precedence over higher-level needs.
