Ecosystem
An ecosystem is a dynamic, self-regulating system comprising all living organisms within a defined area together with the non-living physical environment, functioning as an integrated whole through continuous exchanges of energy and matter.
Overview
Arthur Tansley's formalization of the term in 1935 marked a pivotal shift from studying individual species to analyzing the system-level processes — nutrient cycling, energy flow through trophic levels, decomposition, and feedback mechanisms — that govern biological communities. This advance established that biological processes cannot be meaningfully separated from their physical context.
Why it matters
Ecosystem thinking transformed ecology into a quantitative systems science and profoundly influenced environmental policy through the concept of ecosystem services — the measurable benefits natural systems provide to human societies, including clean water, carbon sequestration, pollination, and flood regulation. It shaped conservation biology, climate modeling, and sustainability economics.
