These products are often sold from the bakery itself. bakery farmyard manure A brewery is a building in which alcoholic beverages are produced by brewing, that is, steeping a starch source (commonly cereal grains) in water and fermenting the resulting sweet liquid with yeast. At times, the products are also sold from the brewery. brewery rye grass silage stable manure potato silage compost soil A portion of soil which is part of a cropland or a rangeland biome. farm soil A portion of environmental material is a fiat object part which forms the medium or part of the medium of an environmental system. A portion of environmental material is a fiat object which forms the medium or part of the medium of an environmental system. environmental material Anthropogenic material in or on which organisms may live. anthropogenic environmental material A liquid or semi-liquid mixture of water and some combination of soil, silt, and clay. mud water well A naturally occurring granular material composed of finely divided rock and mineral particles. sand Gravel is an environmental material which is composed of pieces of rock that are at least two millimeters (2mm) in its largest dimension and no more than 75 millimeters. gravel The ocean biome comprises major bodies of saline water, principal components of the hydrosphere. Approximately 71% of the Earth's surface is covered by ocean, a continuous body of water that is customarily divided into several principal oceans and smaller seas. More than half of this area is over 3,000 metres (9,800 ft) deep. Average oceanic salinity is around 35 parts per thousand (ppt) (3.5%), and nearly all seawater has a salinity in the range of 30 to 38 ppt. ocean biome Environmental material derived from living organisms. organic material A forest biome is a terrestrial biome which includes, across its entire spatial extent, densely packed vegetation which strongly limits light penetration to the forest floor. forest biome A woodland biome is a terrestrial biome which includes, across its entire spatial extent, woody plants spaced sufficiently far apart to allow light penetration to support communities of herbaceous plants or shrubs living closer to the woodland floor. woodland biome A shrubland biome is a terrestrial biome which includes, across its entire spatial extent, dense groups of shrubs. shrubland biome A grassland biome is a terrestrial biome which includes, across its entire spatial extent, an unbroken layer of grasses (Gramineae), sedges (Cyperaceae) or rushes (Juncaceae). grassland biome A desert biome is a terrestrial biome which loses more liquid water by evapotranspiration than is supplied by precipitation and includes communities adapted to these conditions. desert biome A tundra is a terrestrial biome which includes, across its spatial extent, only low-growing vegetation such as dwarf shrubs, sedges and grasses, mosses, and lichens. Tundra biomes rarely have monthly average temperatures above 10 degrees Celsius and have low evapotranspiration ratios. tundra biome A mangrove biome is a terrestrial biome which includes, across its spatial extent, mangrove plants (Rhizophoraceae). Mangrove plants are able to withstand high levels of salinity as well as regions of anoxia and frequent tidal inundation. Mangrove biomes often occur near tropical and sub-tropical estuaries and depositional marine coastal environments where fine sediments (often with high organic content) collect in areas protected from high energy wave action. mangrove biome An anthropogenic terrestrial biome is a terrestrial biome which has community structures determined by human activity. anthropogenic terrestrial biome A cropland biome is an anthropogenic terrestrial biome which is primarily used for agricultural activity and which contains no village or larger human settlement. cropland biome A village biome is an anthropogenic terrestrial biome which contains settlements such as villages, towns, and/or small cities and which is primarily used for agricultural activity. village biome A rangeland biome is an anthropogenic terrestrial biome which is primarily used for the rearing and grazing of livestock. rangeland biome A dense settlement biome is an anthropogenic terrestrial biome which is primarily used for human habitation, recreation, and industry within built structures with little other land use. dense settlement biome freshwater lake biome freshwater river biome A system which has the disposition to environ one or more material entities. environmental system A site which has its extent determined by the presence or influence of one or more components of an environmental system or the processes occurring therein. environmental zone A building floor is a surface layer which is part of a building and used for walking. building floor A drylot is an enclosure of limited size usually bare of vegetation and used for fattening livestock. drylot A feedlot is a plot of land on which livestock are fattened for market feedlot An animal house which is only partially surrounded by a building envelope. open animal house An animal house which has a complete building envelope. closed animal house A manufactured cage which may be used to confine, contain, or protect an animal. animal cage A petting zoo is a zoological garden which contains domesticated non-human animals and some wild non-human animals that are docile enough for humans to touch and feed. petting zoo An artificial channel which transports unwanted water or waste liquids away from their source, either to a more useful area, a receptacle, or into sewers or stormwater mains as waste discharge to be released or processed. plumbing drain A facility in which non-human animals are slaughtered and processed for human consumption. abattoir A building which is used to care for a human child during the working day by a person, outside the child's immediate family, other than that child's legal guardians. day care building A building in which fish are subject to a series of operations to prepare them for human consumption. fish processing building A building in which nursing aides and skilled nurses provide care and treatment to residents who have significant difficulty coping with the required activities of daily living. nursing home A human house which serves as a long-term shelter for its inhabitants and within which they store personal property. residential building A building within which food and drink are prepared and served to customers in exchange for money or other goods and/or services. restaurant A part of an ecosystem which may be or has been used for one or more overnight stays by humans sheltering in tents, camper vans, caravans, or improvised shelters. campground A campground which has been modified by humans to provide and maintain facilities for camping such as fire pits, road access, latrines, and garbage bins. dedicated campground A campground which has no pre-existing facilities installed or maintained by humans, usually found outside of anthropised ecosystems. impromptu campground A manufactured product which may hold a volume of heated water suitable for one or more humans to bathe in, usually for the purposes of hydrotherapy or pleasure. hot tub Manure which has been collected directly or indirectly from dairy cattle, as from flushing of manure from concrete feed lanes, free stalls, and milking facilities. bovine dairy liquid manure Manure which has been subjected to a natural process of 'rotting' or decomposition of its organic matter content by microorganisms under controlled conditions. composted animal manure pea vine silage The synthesis by organisms of organic chemical compounds, especially carbohydrates, from carbon dioxide (CO2) using energy obtained from light rather than from the oxidation of chemical compounds. photosynthesis The enzymatic release of energy from inorganic and organic compounds (especially carbohydrates and fats) which either requires oxygen (aerobic respiration) or does not (anaerobic respiration). cellular respiration
