Opposite of generalist; a species with a narrow niche that can tolerate a narrow range of conditions and can use only a few specific resources.

The concept being tested is how species fit into the spectrum from broad to narrow niche breadth. A specialist is a species with a narrow niche: it tolerates only a small range of environmental conditions and relies on a limited set of resources. This tight specialization means the organism is highly efficient within its preferred conditions—for example, a species that depends on a single type of plant or a specific habitat. However, that same specialization makes it vulnerable if those conditions or resources disappear or change. In contrast, a generalist can handle a wide range of environments and exploit many different resources, which is the opposite of the described scenario. Endemic refers to a species that is restricted to a particular place, which is about distribution rather than how narrowly it can survive or what resources it uses. Habitat is the environment itself, not the organism’s breadth of niche or resource use. So the statement describes a specialist: a species with a narrow niche, narrow tolerance, and reliance on only a few specific resources.
