There are seven life processes that tell us that animals are alive. To help us remember them we have found a friend to remind you – Mrs Nerg. Although her name sounds a bit strange, the letters in it stand for the life processes – movement, reproduction, sensitivity, nutrition, excretion, respiration and growth.
