This means that particles are transported from space, with their low concentration, to space with their higher concentration - a process which requires energy. Sometimes this requires transporting substances through barriers (e.g., cell membranes) and against a concentration (or molarity) gradient. We automatically correct concentrations and the amounts of different substances in various areas of our body to preserve homeostasis (a state of the steady internal conditions). What's interesting is that, throughout the day, more energy is consumed by the regulation of fluid volumes and ion levels than in the actual mechanical work of contracting muscles (e.g., breathing). The organs that use the most energy at rest are the brain, the central nervous system and the liver. It's the amount of energy your body needs to support its vital functions: breathing, blood circulation, controlling body temperature, brain and nerve functions to name a few.
