Any material that an organism consumes for sustenance is considered food. The majority of food comes from plants, animals, or fungi and contains vital nutrients like carbs, lipids, proteins, vitamins, and minerals. An organism consumes the material, which is then absorbed by the organism's cells to supply energy, support life, or promote growth. Animals of various species have diverse feeding habits that meet the demands of their metabolisms, which have evolved to fill particular ecological niches in particular geographic contexts.
