Solution:
The nephridia in earthworm are analogous to flamecells of Planaria. Since both of them have excretory functions, so they are analogous to each other. Nematoblasts of Hydra are organs of locomotion, food capture and anchorage. Gills and trachea are organs of respiration in prawn and insects respectively.
