ecosystem-level

The term is a modern scientific compound, formed in the 20th century by combining the established noun 'ecosystem' with the noun 'level'. 'Ecosystem' itself is a mid-20th century blend of 'ecology' (from Greek oikos, "household," and -logia, "study of") and 'system'. 'Level' entered English via French, tracing back to the Latin libella, a tool for checking horizontality, which metaphorically extended to mean a standard or plane of existence. Thus, 'ecosystem-level' logically constructs its meaning by applying the concept of a specific scale or plane of analysis ('level') to the integrated community of living organisms and their physical environment ('ecosystem').
