Concept:An ecosystem is the interaction between living organisms and their non-living environment. The term was first introduced by a specific scientist.Explanation:The term "ecosystem" was coined by A. G. Tansley in 1935. He defined it as a system formed by the interaction of all living organisms with their physical surroundings. This concept combines biotic (living) and abiotic (non-living) components into a single unit. Other scientists have different roles: Haeckel coined "ecology", Odum is called the father of modern ecology, and Whittaker contributed to classification. Tansley is the correct answer for the origin of the word "ecosystem".
