ecosystem : the complex of a community of organisms and its environment functioning as an ecological unit — Webster

Encyclopedia

Ecosystem is a community made up of living organisms and nonliving components such as air, water, and mineral soil. Ecosystems can be studied in two different ways. They can be thought of as interdependent collections of plants and animals, or as structured systems and communities governed by general rules. The living (biotic) and non-living (abiotic) components interact through nutrient cycles and energy flows. Ecosystems include interactions among organisms, and between organisms and their environment. Ecosystems can be of any size but each ecosystem has a specific, limited space. — Wikipedia

Types of Environmental Ecosystems (Amy Harris, Sciencing)

Biome is a community of plants and animals that have common characteristics for the environment they exist in. They can be found over a range of continents. Biomes are distinct biological communities that have formed in response to a shared physical climate. “Biome” is a broader term than “habitat”; any biome can comprise a variety of habitats.

A ‘biota’ is the total collection of organisms of a geographic region or a time period, from local geographic scales and instantaneous temporal scales all the way up to whole-planet and whole-timescale spatiotemporal scales. The biotas of the Earth make up the biosphere. — Wikipedia

Science

Ecology 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. — Wikipedia

    Forests in the Pacific Northwest will be less vulnerable to drought and fire over the next three decades than those in the Rocky Mountains and Sierra Nevada, computer modeling shows. […]

  • Climate change/biodiversity loss: Inseparable...
    on November 15, 2018 at 7:49 pm

    Demand for biofuels to fight climate change clouds the future for biodiversity. The demand could cause a 10- to 30-fold expansion of green energy-related agricultural land use, adding crushing pressure on habitat for plants and animals and undermining the essential diversity of species on Earth. […]

  • Competition for shrinking groundwater
    on November 14, 2018 at 7:43 pm

    Groundwater, which has been used to irrigate crops, satiate livestock and quench thirst in general for thousands of years, continues to be a vital resource around the world. […]

    on November 14, 2018 at 6:20 pm

    In the most comprehensive study of its kind, biologists have found that tropical and subtropical forests across South America's Andes Mountains are responding to warming temperatures by migrating to higher, cooler elevations, but probably not quickly enough to avoid the loss of their biodiversity, functional collapse, or even extinction. […]

    on November 19, 2018 at 8:00 pm

    Smoke from widespread fires in Indonesia in the summer and fall of 2015 hung heavily over major urban centers in Southeast Asia, causing adverse health effects for millions of people. The afflicted could not have known that the polluted air they were breathing contained carbon from plants that were alive during the Middle Ages. […]

  • Major natural carbon sink may soon become carbon...
    on November 19, 2018 at 8:00 pm

    Until humans can find a way to geoengineer ourselves out of the climate disaster we've created, we must rely on natural carbon sinks, such as oceans and forests, to suck carbon dioxide out of the atmosphere. These ecosystems are deteriorating at the hand of climate change, and once destroyed they may not only stop absorbing carbon from the atmosphere, but start emitting it. […]

  • From the Arctic to the tropics: Researchers...
    on November 19, 2018 at 4:00 pm

    Which plant species grow where, alongside which others—and why? The diversity of global vegetation can be described based on only a few traits from each species. This has been revealed by a research team led by Martin Luther University Halle-Wittenberg (MLU) and the German Centre for Integrative Biodiversity Research (iDiv) Halle-Jena-Leipzig. In a new study published in the scientific journal Nature Ecology & Evolution, they present the world's first global vegetation database which […]
