An organism with a very narrow range of food preferences is referred to as?

An organism with a very narrow range of food preferences is referred to as stenophagous. This term specifically describes species that have limited dietary habits and require specific types of food to thrive. Stenophagous organisms often occupy specialized niches within an ecosystem because their feeding habits are so restricted.

In contrast, euryphagous organisms can eat a wide variety of foods and are often generalists, able to adapt to different types of food sources. The terms generalist and polyphagous also indicate a broad dietary flexibility, focusing on species that can consume many types of foods. This adaptive strategy enables them to thrive in various environments where food availability may fluctuate. Thus, stenophagous distinguishes those that depend on a narrow set of food resources, making it the accurate term in this context.
