Question: Information:  - A population is the number of all the organisms of the same group or species, which live in a particular geographical area, and have the capability of interbreeding.  - The Brachycephalidae are a family of small frogs confined to cloud forests in southern Brazil. The family is composed of two externally quite different genera: the colourful and plump saddleback toads ("Brachycephalus"), and the slimmer and more drab genus "Ischnocnema", with some species also ranging into northeast Argentina. The family is mainly defined by molecular characteristics, and are linked by few anatomical features. It was erected from two genera of the previously large family Eleutherodactylidae, which is now split into four families.  - Brazil, officially the Federative Republic of Brazil, is the largest country in both South America and Latin America. As the world's fifth-largest country by both area and population, it is the largest country to have Portuguese as an official language and the only one in the Americas. Bounded by the Atlantic Ocean on the east, Brazil has a coastline of . It borders all other South American countries except Ecuador and Chile and covers 47.3% of the continent's land area. Its Amazon River basin includes a vast tropical forest, home to diverse wildlife, a variety of ecological systems, and extensive natural resources spanning numerous protected habitats. This unique environmental heritage makes Brazil one of 17 megadiverse countries, and is the subject of significant global interest and debate regarding deforestation and environmental protection.  - Ischnocnema is a genus of frogs from east Brazil and northeast Argentina. They comprise the former "Eleutherodactylus" from this region, but they are closer to "Brachycephalus" than the "true" "Eleutherodactylus". Consequently, they are now placed in their own genus "Ischnocnema" in the family Brachycephalidae.  - 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.  - Ischnocnema manezinho is a species of frog in the Brachycephalidae family . It is endemic to Brazil . Its natural habitat is subtropical or tropical moist lowland forests . It is threatened by habitat loss .  - The Eleutherodactylidae are a family of direct-developing frogs native to northern South America, the Caribbean, and southernmost North America. They are sometimes known under common name rain frogs. Formerly a subfamily Eleutherodactylinae of the Leptodactylidae family, it was raised to the family status following a major revision of New World direct-developing frogs in 2008. As currently defined, the family has more than 200 species (as of 2014, 206 or 207 species).  - The saddleback toads are a genus of small, colourful toads the family Brachycephalidae in the order Anura. As traditionally defined, the family is often limited to just one genus, Brachycephalus, but it is closely related to "Ischnocnema", which therefore is placed in the family in recent treatments. "Brachycephalus" species are tiny, often yellow frogs that are native to Atlantic Forest in southeastern Brazil. In at least one species, "B. ephippium", the bright colours are aposematic, warning potential predators of its toxicity, specifically tetrodotoxin.  - Chile, officially the Republic of Chile, is a South American country occupying a long, narrow strip of land between the Andes to the east and the Pacific Ocean to the west. It borders Peru to the north, Bolivia to the northeast, Argentina to the east, and the Drake Passage in the far south. Chilean territory includes the Pacific islands of Juan Fernández, Salas y Gómez, Desventuradas, and Easter Island in Oceania. Chile also claims about of Antarctica, although all claims are suspended under the Antarctic Treaty.  - Food is any substance consumed to provide nutritional support for the body. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism and assimilated by the organism's cells to provide energy, maintain life, or stimulate growth.  - Argentina, officially the Argentine Republic, is a federal republic in the southern half of South America. Sharing the bulk of the Southern Cone with its neighbor Chile to the west, the country is also bordered by Bolivia and Paraguay to the north, Brazil to the northeast, Uruguay and the South Atlantic Ocean to the east, and the Drake Passage to the south. With a mainland area of , Argentina is the eighth-largest country in the world, the second largest in Latin America, and the largest Spanish-speaking one. The country is subdivided into twenty-three provinces (singular "provincia") and one autonomous city ("ciudad autónoma"), Buenos Aires, which is the federal capital of the nation as decided by Congress. The provinces and the capital have their own constitutions, but exist under a federal system.  - Animals are multicellular, eukaryotic organisms of the kingdom Animalia (also called Metazoa). The animal kingdom emerged as a basal clade within Apoikozoa as a sister of the choanoflagellates. Sponges are the most basal clade of animals. Animals are motile, meaning they can move spontaneously and independently at some point in their lives. Their body plan eventually becomes fixed as they develop, although some undergo a process of metamorphosis later in their lives. All animals are heterotrophs: they must ingest other organisms or their products for sustenance.  - A habitat is an ecological or environmental area that is inhabited by a particular species of animal, plant, or other type of organism. The term typically refers to the zone in which the organism lives and where it can find food, shelter, protection and mates for reproduction. It is the natural environment in which an organism lives, or the physical environment that surrounds a species population.
