Ecology is study of the interactions of living organisms with one another and with the non-living elements of their environment. Objects of study include interactions of organisms with each other and with abiotic components (physical rather than biological; not derived from living organisms) of their environment. Topics of interest include the biodiversity, distribution, biomass, and populations of organisms, as well as cooperation and competition within and between species. An important focus for ecologists is to improve the understanding of how biodiversity affects ecological function.
