Metabolism consists of all the energy transformation reactions in an organism, which includes both anabolism (building up molecules) and catabolism (breaking down molecules). While energy from food is a common source of energy for metabolism, not all organisms depend on this source (e.g. photosynthetic organisms can derive energy from sunlight). Metabolism does not necessarily use all of an organism's resources and while it helps manage entropy, it does not prevent the overall increase of entropy in the universe.
