Step-by-step explanation:
Needs are the requirements of a person to live his life. Needs are basically the basic necessities that a person must have in order to live. Such needs include Food, Water, Clothes, Shelter, Air, etc. According to Maslow, there are 5 levels of Needs. If the above mentioned needs of a person are fulfilled, he moves towards the other next level. He needs to be fully safe and secured. Then he tries to find the belongings, the love, the affection, etc. After the fulfillment of these needs, he move towards the finding of the esteem needs of himself, and then move towards the self actualization level of the needs. But the needs without which a person can't live are Food, Air, Water, Clothes, Shelter and security. These are the physiological needs.
