Some parasites include: 

• Stomach and gut worms (threadworm, hookworm) 

• Skin mites(scabies) 

• Hair and body lice 

• Protozoa (Giardia) 

Heterotrophic nutrition can be one of three types: 

holozoic, saprophytic or parasitic. Parasitic nutrition is where an organism lives in or on its host and acquires nutrition at the expense of its host. Unlike commensalism, the parasite causes some harm to its host. Some more examples include cuscuta plant, tapeworms etc.
