The process is only homologous to eating at the level of single-celled organisms; in multicellular animals, the process has been adapted to eliminate debris and pathogens, as opposed to taking in fuel for cellular processes, except in the case of the Trichoplax. In immune system Phagocytosis in mammalian immune cells is activated by attachment to Pathogen-associated… (More on Phagocytosis)
