What type of enemy of survival is hunger classified as?

Hunger is classified as a physical enemy of survival because it directly impacts the body’s physiological needs. Survival requires fulfilling basic human needs, and hunger indicates that the body lacks essential nutrients and energy necessary for functioning. When an individual does not have enough food, it leads to physical weakness, impaired cognitive function, and decreased overall capability to perform necessary tasks. Effective survival strategies must primarily address physical needs, such as obtaining food and water, to maintain health and ensure the body's proper functioning. Other options, while relevant to survival in different contexts, do not pertain to the immediate, tangible effects that hunger has on the body.
