In biology, detritus (/ d ɪ ˈ t r aɪ t ə s / or / d ɛ ˈ t r ɪ t ə s /) is organic matter made up of the decomposing remains of organisms and plants, and also of feces. Detritus usually hosts communities of microorganisms that colonize and decompose (remineralise) it. Such microorganisms may be decomposers, detritivores, or coprophages.
Debris (UK: / ˈ d ɛ b r iː, ˈ d eɪ b r iː /, US: / d ə ˈ b r iː /) is rubble, wreckage, ruins, litter and discarded garbage/refuse/trash, scattered remains of something destroyed, or, as in geology, large rock fragments left by a melting glacier, etc. Depending on context, debris can refer to a number of different things.
Placental mammals expel urine from the bladder through the urethra during urination. [1]Metabolic wastes or excrements are substances left over from metabolic processes (such as cellular respiration) which cannot be used by the organism (they are surplus or toxic), and must therefore be excreted.
Plant litter, which can be made up of fallen leaves, twigs, seeds, flowers, and other woody debris, makes up a large portion of above ground net primary production of all terrestrial ecosystems. Fungus plays a large role in cycling the nutrients from the plant litter back into the ecosystem.
Space debris is classified by size and operational purpose, and divided into four main subsets: inactive payloads, operational debris, fragmentation debris and microparticulate matter. [3] Inactive payloads refer to any launched space objects that have lost the capability to reconnect to its corresponding space operator; thus, preventing a ...
The EPA defines this type of waste as "Construction and Demolition (C&D) debris is a type of waste that is not included in municipal solid waste (MSW)." [12] Items typically found in C&D include but are not limited to steel, wood products, drywall and plaster, brick and clay tile, asphalt shingles, concrete, and asphalt. Generally speaking ...
The basic mechanism of debris fallout is debris lofted by a tornado's updraft winds high into the atmosphere. [4] Charles E. Anderson completed the first study focusing on debris fallout on the F5 1984 Barneveld tornado, which produced a large survey revealing a trail of paper debris as wide as 23 mi (37 km) at 110 mi (180 km) from Barneveld and a roughly 85 mi (137 km) long path of heavy ...
Due to the distinct chemistry and biology that determine what prevents them from settling, organisms are also classified as hard- or soft-fouling types. Calcareous (hard) fouling organisms include barnacles , encrusting bryozoans , mollusks such as zebra mussels , and polychaete and other tube worms .
