Which level of Maslow's hierarchy focuses on basic needs such as breathing, food, and sleep?

The level of Maslow's hierarchy that focuses on basic needs such as breathing, food, and sleep is the physiological level. This foundational tier is essential because these needs are the most basic requirements for human survival. Without meeting these needs, individuals cannot move on to higher levels of the hierarchy, which include safety, love and belonging, esteem, and self-actualization.

Maslow posited that human motivation is driven by the fulfillment of these needs in a sequential manner; only when physiological needs are adequately met can one pursue safety and security, followed by social connections, esteem from others, and ultimately, self-fulfillment and personal growth. The emphasis on the physiological level highlights the importance of these fundamental needs in establishing a stable platform for overall health and well-being.
