Question

explain nutrition in protozoans​

Answer 1

As almost all protozoans are heterotropic and parasitic, Protozoa may take in food by osmotrophy, absorbing nutrients through their cell membranes; or they may feed by phagocytosis, either by engulfing particles of food with pseudopodia (as amoebae do), or taking in food through a mouth-like aperture called a cytostome. All protozoa digest their food in stomach-like compartments called vacuoles. The digested food is then directly assimilated for nutrition by cell.
