The diversity of life is organized into different habitats, from terrestrial (middle) to aquatic ecosystems . </Td> </Tr> <P> Ecology (from Greek: οἶκος, "house", or "environment"; - λογία, "study of") is the branch of biology which studies the interactions among organisms and their environment . Objects of study include interactions of organisms with each other and with abiotic components 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 . Ecosystems are dynamically interacting systems of organisms, the communities they make up, and the non-living components of their environment . Ecosystem processes, such as primary production, pedogenesis, nutrient cycling, and niche construction, regulate the flux of energy and matter through an environment . These processes are sustained by organisms with specific life history traits . Biodiversity means the varieties of species, genes, and ecosystems, enhances certain ecosystem services . </P> <P> Ecology is not synonymous with environmentalism, natural history, or environmental science . It overlaps with the closely related sciences of evolutionary biology, genetics, and ethology . An important focus for ecologists is to improve the understanding of how biodiversity affects ecological function . Ecologists seek to explain: </P>
