Parasitic nutrition is a mode of heterotrophic nutrition where an organism, known as a parasite, lives on the body surface or inside the body of another organism, known as a host. Parasites obtain their nutrition by absorbing nutrients directly from the host's tissues or bloodstream.

Parasites have evolved various strategies to obtain nutrients from their hosts. Some parasites feed on the host's blood, while others feed on the host's tissues or bodily fluids. Some parasites secrete digestive enzymes that break down their food before absorption.

Parasitic nutrition is an important adaptation that allows parasites to thrive in a wide range of environments. However, it can also be harmful to the host, causing damage to tissues and organs and leading to disease.
