free-living! We don't live on or in other organisms.
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.

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.
Humans are considered free-living organisms, as we are capable of obtaining our own food and energy from the environment. While we rely on resources from the environment to survive, we are not considered parasitic because we do not solely depend on a single host for our survival.
