Answer 2

Answer:

The biological process involved in the removal of harmful nitrogenous metabolic wastes from the body is called excretion. Various metabolic activities in animal body generate these nitrogenous waste materials which should be excreted out.

→ Complex multi-cellular animals use specialised excretory organs to perform the same function.
