Biomonitoring: the gathering of biological information in both the laboratory and the field for the purpose of making an assessment or decision or in determining whether quality objectives are being met. Ecosystem: any unit that includes all of the organisms (i.e. the community) in a given area interacting with the physical environment so that a flow of energy leads to clear defined trophic structure, biodiversity and material cycles (i.e. exchange of material between living and non-living parts) within the ecosystem. Geomorphology: the study
