STPM Biology - chapter 6: Revision essay question 3

3. How does the nutrition of the named endoparasite differ from the nutrition of Mucor?

Answer


                    -Taenia is an endoparasitic tapeworm living in the human gut and may harm the host.       
                     Mucor is a saprotroph living on dead decaying matter.
                    -The parasitic tapeworm absorbs soluble predigested food from the living host.
                      Exracellular digestion is not required. The fungal hyphae of Mucor penetrate th food
                      source. Enzymes are secreted externally (extracellular digestion) to digest the
                      complex food into soluble substances for absorption.
