A tapeworm exhibits a parasitic mode of nutrition. This means that it feeds off the nutrients of another living organism, known as the host, to survive and grow. Tapeworms attach themselves to the inner lining of the host's intestines, and absorb the nutrients from the food that the host has eaten, depriving the host of these nutrients. This type of feeding is different from holozoic nutrition, which involves the intake of solid food and the digestion of that food within the organism's body.
