Explanation:

There are five different levels of Maslow’s hierarchy of needs. Let's take a closer look at Maslow’s needs starting at the lowest level, known as physiological needs.  Maslow's hierarchy is most often displayed as a pyramid. The lowest levels of the pyramid are made up of the most basic needs, while the most complex needs are at the top of the pyramid.

Needs at the bottom of the pyramid are basic physical requirements including the need for food, water, sleep, and warmth. Once these lower-level needs have been met, people can move on to the next level of needs, which are for safety and security.
