Every living organism, from the smallest bacterium to the largest whale, depends on a continuous supply of energy to survive. This fundamental requirement is why intake of food is considered so important, as it provides the essential fuel and materials needed for all biological processes, from growth and repair to immune function.

Approximately 10% of the energy consumed by an organism is transferred to the next trophic level. This fundamental transfer of energy begins with food, making the question of why food is essential for living beings a foundational concept in biology that explains how organisms get the fuel needed for survival and function.

According to the World Health Organization, better nutrition is linked to improved infant, child, and maternal health, stronger immune systems, and longevity. This critical fact highlights the profound answer to **what is the importance of nutrition for living beings**, emphasizing its role in overall development and well-being, powering every biological process from the cellular level upwards.
