Who coined the term "ecosystem"?

The term "ecosystem" was coined by AG Tansley in 1935. Tansley was an ecologist who aimed to describe the complex interactions between living organisms and their physical environment as a cohesive system. This concept allowed for a better understanding of how energy flow and nutrient cycling occur within a community of organisms and their surroundings. By introducing this term, Tansley emphasized the interconnectedness of biotic and abiotic components, laying the groundwork for future ecological studies. This foundational concept remains essential in ecology today, as it helps researchers and students understand environmental interdependencies and the impacts of human activity on ecosystems.
