Final answer:
Food, shelter, and warmth are categorized as physiological needs in Maslow's hierarchy, representing the most basic requirements for survival.
Step-by-step explanation:
Food, shelter, and warmth represent physiological needs in Maslow's hierarchy of needs. These needs are the most fundamental for survival and are found at the base of the pyramid. The hierarchy proceeds to safety needs, social needs such as love and belonging, esteem needs, and finally self-actualization at the peak, where an individual reaches their full potential. Maslow's theory suggests that lower-level needs like physiological and safety need to be met before higher-level needs can be fully addressed.
