The basic physiological needs are probably fairly apparent – these include the things that are vital to our survival. Some examples of the physiological needs include:
Food
Water
Breathing
Homeostasis
In addition to the basic requirements of nutrition, air and temperature regulation, the physiological needs also include such things as shelter and clothing. Maslow also included sexual reproduction in this level of the hierarchy of needs since it is essential to the survival and propagation of the species.
