          What do earthworms eat?
         They feed on the remains


         of dead plants found in the


         ground.  They eat soil as


         they tunnel, taking food

         from it  and passing the
        unwanted  soil out of  their

         bodies.  They also feed on

        leaves from the surface of


         the ground. They pull these


         down into their burrows to
        eat them in safety.






         How do worms breathe?


         They do not breathe as we  do, as they
        have no lungs.  Instead, God has

        designed that they take in oxygen
         through tiny pores in their skin.   As


         worms tunnel, air gets into the soil.
        When there is a  heavy downpour, the

        worm’s burrow may fill with water and so

         the worm will come to the surface to

         breathe.


                         How do worms see underground?


          A worm cannot see, nor hear nor smell.  However,

        it can feel vibrations in the soil and so it stays


         away from danger.  A worm can ‘feel’ when it is

         raining, because of the vibrations of rain drops on

          the soil.                                        88
