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.

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.

In a multicellular organism's immune system, phagocytosis is a major mechanism used to remove pathogens and cell debris. The ingested material is then digested in the phagosome. Bacteria, dead tissue cells, and small mineral particles are all examples of objects that may be phagocytized.
Microscopic examination shows amorphous granular debris enclosed within a distinctive inflammatory border. [7] Some granulomas contain this pattern of necrosis. [10] Fat necrosis is specialized necrosis of fat tissue, [10] resulting from the action of activated lipases on fatty tissues such as the pancreas.
The victims represent a cross section of the legions who traverse America’s congested airways on any given day, including a biology professor and popular soldiers, longtime airline pilots and ...
Coarse woody debris (CWD) or coarse woody habitat (CWH) refers to fallen dead trees and the remains of large branches on the ground in forests [1] and in rivers or wetlands. [2] A dead standing tree – known as a snag – provides many of the same functions as coarse woody debris.
