Answer 2

Answer:

Food provides people the energy and nutrients they need to grow and develop, gain strength, and work productively.

Explanation:

• Food is one of the basic needs of human life. It provides people the energy and nutrients they need to grow and develop, gain strength, and work productively.
• According to Abraham Maslow's Hierarchy of Needs, a motivational psychological theory, food is an innate physiological need along with water, warmth, and rest.
• Organisms need to take food to get energy and perform life processes. A living organism undergoes many life processes like nutrition, respiration, digestion, transportation, excretion, blood circulation, and reproduction. To perform all these life processes, the organism needs energy and nutrients.
