Context: In biology, an organism is any contiguous living system, such as an animal, plant, fungus, archaeon, or bacterium. All known types of organisms are capable of some degree of response to stimuli, reproduction, growth and development and homeostasis. An organism consists of one or more cells; when it has one cell it is known as a unicellular organism; and when it has more than one it is known as a multicellular organism. Most unicellular organisms are of microscopic scale and are thus loosely described as microorganisms. Humans are multicellular organisms composed of many trillions of cells grouped into specialized tissues and organs., A fungus (plural: fungi or funguses) is any member of the group of eukaryotic organisms that includes unicellular microorganisms such as yeasts and molds, as well as multicellular fungi that produce familiar fruiting forms such as mushrooms and bracket fungi. These organisms are classified as a kingdom, Fungi, which is separate from the other eukaryotic life kingdoms of plants and animals., Binomial nomenclature (also called binominal nomenclature or binary nomenclature) is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (which may be shortened to just "binomial"), a binomen or a scientific name; more informally it is also called a Latin name. The first part of the name identifies the genus to which the species belongs; the second part identifies the species within the genus. For example, humans belong to the genus "Homo" and within this genus to the species "Homo sapiens". The "formal" introduction of this system of naming species is credited to Carl Linnaeus, effectively beginning with his work "Species Plantarum" in 1753. But Gaspard Bauhin, in as early as 1623, had introduced in his book "Pinax theatri botanici" (English, "Illustrated exposition of plants") many names of genera that were later adopted by Linnaeus., The fungus-growing ants (tribe Attini) comprise all the known fungus-growing ant species participating in ant-fungus mutualism. Leafcutter ants, including "Atta" and "Acromyrmex", make up two of the genera., The Formicinae are a subfamily within the Formicidae containing ants of moderate evolutionary development., Acromyrmex is a genus of New World ants of the subfamily Myrmicinae. This genus is found in South America and parts of Central America and the Caribbean Islands, and contains 31 known species.
Commonly known as "leafcutter ants" they comprise one of the two genera of advanced attines within the tribe Attini, along with "Atta"., Ants are eusocial insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from wasp-like ancestors in the Cretaceous period, about 99 million years ago and diversified after the rise of flowering plants. More than 12,500 of an estimated total of 22,000 species have been classified. They are easily identified by their elbowed antennae and the distinctive node-like structure that forms their slender waists., A genus ( genera) is a taxonomic rank used in the biological classification of living and fossil organisms in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus., Sericomyrmex is a genus of fungus - growing ants in the subfamily Formicinae ., Leafcutter ants, a non-generic name, are any of 47 species of leaf-chewing ants belonging to the two genera "Atta" and "Acromyrmex".
These species of tropical, fungus-growing ants are all endemic to South and Central America, Mexico, and parts of the southern United States., Subject: sericomyrmex, Relation: parent_taxon, Options: (A) acromyrmex (B) animal (C) atta (D) attini (E) formicidae (F) formicinae (G) fungi (H) homo (I) insects (J) myrmicinae (K) plant
