Ecosystem
An ecosystem is a dynamic system comprising a community of living organisms interacting with their non-living physical environment through continuous exchanges of energy and matter.
Overview
Arthur Tansley's formalization of the term in 1935 shifted focus from individual species to system-level processes governing biological communities. Core processes include nutrient cycling, energy flow across trophic levels, decomposition, and feedback mechanisms that link biological communities to their abiotic surroundings. This framework established that biological processes cannot be analyzed separately from their physical context.
Why it matters
Ecosystem thinking established a quantitative approach in ecology and informs environmental policy through the concept of ecosystem services. These services include measurable benefits natural systems provide to human societies, such as water filtration, carbon storage, pollination, and flood regulation. This framework is applied across conservation biology, climate modeling, and sustainability economics.
