Answer 1

An amoeba digests food by engulfing particles through phagocytosis to form a food vacuole, then uses lysosomal enzymes to break food down inside the cell (intracellular digestion). A mouse uses a multicellular digestive system—mouth, stomach, intestines, and accessory organs—that secretes enzymes to break down food outside cells (extracellular digestion) and then absorbs nutrients into the bloodstream. In the mouse, specialized tissues and organs coordinate digestion, absorption, and distribution of nutrients to many cells, whereas the single amoeba must perform all these tasks within one cell.
