According to the law of conservation of energy, the total energy of an isolated system remains constant over time. Understanding this principle is key to identifying which of the following factors do not contribute to total energy. While many factors can affect specific energy forms, only factors that are not part of the fundamental energy forms of a closed system, such as a system's color or density, are irrelevant to its total energy.

According to the World Health Organization, physical and economic access to food is a cornerstone of food security. Beyond mere availability, however, numerous physical factors profoundly influence the specific food choices people make daily. These influences range from internal biological signals to external environmental cues, creating a complex interplay that guides our dietary decisions and health outcomes.

According to the World Food Programme, climate-related disasters and environmental changes are major drivers of global hunger. These and other physical factors can lead to food insecurity by destabilizing food systems and destroying agricultural productivity.
