Physiological needs and safety needs are higher-order needs in Maslow's hierarchy of human needs.

Maslow's Hierarchy

A theory in psychology proposed by Abraham Maslow, organizing human needs into a five-level pyramid, from basic physiological needs to self-actualization.

Physiological Needs

The basic, essential life needs such as food, water, and shelter that must be met in order for an individual to survive and function properly.

Safety Needs

The second level in Maslow's hierarchy of needs, encompassing the human desire for security, safety, and physical well-being.
