| Maslows heirarchy of needs; Five levels are.. | physiologic, safety and security, love and belonging, self esteem, self actualization. |
| Physiological needs("The Physical needs") are classified as... | The needs for oxygen, fluids,nutrition, life-sistaining enviormental temperature, elimination, shelter, rest and sex. Physilogic needs are the most fundamental because they sustain life. Individuals cannot live without air, water, and food. |
