List and explain the five survival needs of humans

What will be an ideal response?


1. Nutrients include carbohydrates, proteins, fats, and vitamins and minerals, which are taken in via the diet for energy and cell building.
2. Oxygen is required to release energy from food.
3. Water accounts for 60 to 80 percent of the body weight, and provides the basis for various body fluids.
4. Normal body temperature should be around 37°C or 98°F. When body temperature becomes too high or too low, physiological activities cease, primarily because chemical reactions are affected.
5. Appropriate atmospheric pressure is the force exerted on the surface of the body by the weight of air; it is essential for normal operation of the respiratory system and breathing.
