    2. Ecosystem Definition: biotic community and abiotic environment functioning as a system. Includes organism-complex and whole complex of physical factors. Ecosystem ecologist: Forest is a system composed of autographs, heterographs, and abiotic environment, each component processing and exchanging energy and matter. Inputs: exchanges from the surrounding environment into the ecosystem Outputs: exchange from inside ecosystem to the surrounding environment Closed ecosystem: an ecosystem with no inputs and outputs Open ecosystem: an ecosystem with inputs and outputs Ecosystem ecology: exchanges of energy and matter between ecosystem and environment and among components within the ecosystem (energy flow and nutrient cycling). Community ecology study pattern and process within the community, mostly species distribution and abundance, how commnnity structure changes along landscape and time.Community ecology study pattern and process within the community, mostly species distribution and abundance, how commnnity structure changes along landscape and time.
