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

    Out with the old, in with the new, as the New Year's saying goes, but not where the marine environment is concerned. Researchers from Japan have discovered that ocean acidification keeps algal communities locked in a simplified state of low biodiversity.

    Mangroves are salt-tolerant plants found in intertidal areas throughout much of the world's tropical and subtropical coastlines. Mangrove ecosystems are highly variable, ranging from sparse, stunted shrubs to dense stands of thick-stemmed tall trees.

    on January 14, 2021 at 9:30 pm

    Climate change impacts, affecting primarily ecosystems' functions and consequently human sectors, have become a crucial topic. Observed and expected variations in climate conditions can in fact undermine the ecosystems' ecological equilibrium: average climate patterns, mainly represented by intra-annual (monthly to seasonal) temperature and precipitation cycle, directly influence the distribution, abundance and interactions of biological species.
