Decomposition is the process by which organic substances are broken down into simpler matter.
 The process is a part of nutrient cycle and is essential for recycling the finite matter that occupies physical space in the biosphere.
 Bodies of living organisms begin to decompose shortly after death.
 Animals, such as worms, also help decompose the organic materials.
 Organisms that do this are known as decomposers. Although no two organisms decompose in the same way, they all undergo the same sequential stages of decomposition.
 The science which studies decomposition is generally referred to as "taphonomy" from the Greek word "taphos", meaning tomb.
A trackway is an ancient route of travel for people or animals.
 In biology, a trackway can be a set of impressions in the soft earth, usually a set of footprints, left by an animal.
 A fossil trackway is the fossilized imprint of a trackway, a type of trace fossil.
 Trackways have been found all over the world.
 They are especially valuable for determining some characteristics of life-forms, such as behavior.
 Thus some trackways for hominids in Africa showed that they lived together and were not solitary.
 The study of trackways is an aspect of ichnology, the study of marks left by living organisms.
 Since identifying the makers of trackways has not ordinarily proved possible, trackway-makers are given the conventional genus name Ichniotherium, "marking creature".
Biological warfare (BW)—also known as germ warfare—is the use of biological toxins or infectious agents such as bacteria, viruses, and fungi with the intent to kill or incapacitate humans, animals or plants as an act of war.
 Biological weapons (often termed "bio-weapons", "biological threat agents", or "bio-agents") are living organisms or replicating entities (viruses, which are not universally considered "alive") that reproduce or replicate within their host victims.
 Entomological (insect) warfare is also considered a type of biological weapon.
 This type of warfare is distinct from nuclear warfare and chemical warfare, which together with biological warfare make up NBC, the military acronym for nuclear, biological, and chemical warfare using weapons of mass destruction (WMDs).
 None of these are conventional weapons, which are deployed primarily for their explosive, kinetic, or incendiary potential.
Delairea is a plant genus within the family Asteraceae.
 It is classified within tribe Senecioneae.
 It contains only one species, Delairea odorata, which was previously included in the genus Senecio as "Senecio mikanioides", and is known as Cape ivy in some parts of the world and German ivy in others.
In biology, phylogenetics (Greek: φυλή, φῦλον - "phylé", "phylon" = tribe, clan, race + γενετικός - "genetikós" = origin, source, birth) is the study of the evolutionary history and relationships among individuals or groups of organisms (e.g. species, or populations).
 These relationships are discovered through phylogenetic inference methods that evaluate observed heritable traits, such as DNA sequences or morphology under a model of evolution of these traits.
 The result of these analyses is a phylogeny (also known as a phylogenetic tree) – a diagrammatic hypothesis about the history of the evolutionary relationships of a group of organisms.
 The tips of a phylogenetic tree can be living organisms or fossils, and represent the "end," or the present, in an evolutionary lineage.
 Phylogenetic analyses have become central to understanding biodiversity, evolution, ecology, and genomes.
A Tullgren funnel, also known as Berlese funnel or Berlese trap, is an apparatus used to extract living organisms, particularly arthropods, from samples of soil.
 The Tullgren funnel works by creating a temperature gradient over the sample such that mobile organisms will move away from the higher temperatures and fall into a collecting vessel, where they perish and are preserved for examination.
 The illustration shows how it works: a funnel (E) contains the soil or litter (D), and a heat source (F) such as an electric lamp (G) heats the litter.
 Animals escaping from the desiccation of the litter descend through a filter (C) into a preservative liquid (A) in a receptacle (B).
 This illustration is merely a schematic, since usually the soil sample will not be crumbled and poured into the funnel (this would inevitably lead to a high amount of soil particles in the preservation fluid requiring laborious work to sort out the soil organisms).
 In fact, the soil sample is placed on a mesh sieve that will allow the soil animals to pass but should retain most of the soil particles.
In biology, cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells. Cells are the basic unit of structure in all organisms and also the basic unit of reproduction.
 With continual improvements made to microscopes over time, magnification technology advanced enough to discover cells in the 17th century.
 This discovery is largely attributed to Robert Hooke, and began the scientific study of cells, also known as cell biology.
 Over a century later, many debates about cells began amongst scientists.
 Most of these debates involved the nature of cellular regeneration, and the idea of cells as a fundamental unit of life.
 Cell theory was eventually formulated in 1839.
 This is usually credited to Matthias Schleiden and Theodor Schwann.
 However, many other scientists like Rudolf Virchow contributed to the theory.
A unicellular organism, also known as a single-celled organism, is an organism that consists of only one cell, unlike a multicellular organism that consists of more than one cell.
 Historically, simple unicellular organisms have been referred to as monads, though this term is also used more specifically to describe organisms of the genus "Monas" and similar flagellate ameboids.
 The main groups of unicellular organisms are bacteria, archaea, protozoa, unicellular algae, and unicellular fungi.
 Unicellular organisms fall into two general categories: prokaryotic organisms and eukaryotic organisms.
 Unicellular organisms are thought to be the oldest form of life, with early protocells possibly emerging 3.8–4 billion years ago.
Eobacterium is an extinct genus of bacteria from the Fig Tree Formation in Africa.
 It is about 3 billion years old, one of the oldest known living organisms.
 The discovery of "Eobacterium" and other Fig Tree organisms in the 1960s helped prove that life existed over three billion years ago.
Hedyotis (starviolet) is a genus of flowering plants in the family Rubiaceae.
 Many species of this genus such as "Hedyotis biflora, H. corymbosa" and "H. diffusa" are well known medicinal plants.
 The hedyotis is native to tropical and subtropical Asia and to islands of the northwest Pacific.
 It comprises about 115 species.
 The type species for the genus is "Hedyotis fruticosa".
