free-living! We don't live on or in other organisms.
Humans are considered free-living animals as they are not obligate parasites that rely on a host for survival. While humans can have parasitic relationships with certain organisms (e.g., bacteria or viruses), they are not classified as parasitic by nature.
Helminthology is the study of parasitic worms, called helminths, that can infect humans and animals. These include roundworms, tapeworms, and flukes. Helminthologists investigate the biology, life cycles, and control of these parasitic organisms.
Yes, but in the form of a parasitic infection
Some examples of organisms that belong to Phylum Nematoda (nematodes) include roundworms, hookworms, pinworms, and filarial worms. These organisms are characterized by their long, slender, unsegmented bodies and are found in a wide range of habitats worldwide. Nematodes can be free-living or parasitic, impacting plants, animals, and humans.
Helminthology is the scientific study of parasitic worms, including flatworms (such as tapeworms) and roundworms (such as hookworms). Researchers in this field study the biology, ecology, epidemiology, and control of these parasites that can infect humans, animals, and plants.

C. Elegans usually live in soil. They are not parasitic they are freeliving. They usually tend to feed on funi and bacteria.

Organisms can be grouped as free-living or parasitic. A parasite is an organism which lives in or on another organism, from which it obtains its food. Since humans do not do this they are not parasitic, and so must be free-living.
Parasites are organisms that live inside humans or other organisms who act as hosts. They are dependent on their hosts because they are unable to produce food or energy for themselves.
Roughly 30% of fungi are known to be parasitic, meaning they obtain nutrients from living organisms. These parasitic fungi can cause various diseases in plants, animals, and humans.
