Final answer:
Maslow's hierarchy of needs theory identifies physiological needs for food, water, clothing, and shelter as the base level of necessities for basic survival, which must be met prior to addressing higher-level needs.
Step-by-step explanation:
According to Maslow's hierarchy of needs theory, the need for basic survival includes requirements such as food, water, clothing, and shelter. These are considered physiological needs and are found at the base of Maslow's pyramid. This level of needs must be satisfied before individuals can move up to fulfilling higher-level needs, such as those related to security, social belonging, esteem, and self-actualization. Maslow's model suggests that these basic needs are fundamentally important and that most of our energy would be directed towards satisfying them if they are not already met.
