Question: Information:  - A biome is a formation of plants and animals that have common characteristics due to similar climates and can be found over a range of continents. Spanning continents, Biomes are distinct biological communities that have formed in response to a shared physical climate. Biomes are distinct from habitats, because any biome can comprise a variety of habitats.  - Plants are mainly multicellular, predominantly photosynthetic eukaryotes of the kingdom Plantae.  - Gallery forests are forests that form as corridors along rivers or wetlands and project into landscapes that are otherwise only sparsely treed such as savannas, grasslands, or deserts.  - The number and type of plants, how leafy they are, and how healthy they are. In places where foliage is dense and plants are growing quickly, the index is high, represented in dark green. Regions where few plants grow have a low vegetation index, shown in tan. The index is based on measurements taken by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASAs Terra satellite. Areas where the satellite did not collect data are gray.  - An ecoregion (ecological region) is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than an ecozone. All three of these are either less or greater than an ecosystem. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point).  - A municipality is usually a single urban administrative division having corporate status and powers of self-government or jurisdiction as granted by national and state laws, to which it is subordinate. It is to be distinguished from the county, which may encompass rural territory and/or numerous small communities such as towns, villages and hamlets. The term "municipality" may also mean the governing or ruling body of a given municipality. A municipality is a general-purpose administrative subdivision, as opposed to a special-purpose district. The term is derived from French "municipalité" and Latin "municipalis".  - São Paulo ("Saint Paul" in English) is a municipality located in the southeast region of Brazil. The metropolis is an alpha global cityas listed by the GaWCand is the most populous city in Brazil, the Americas, and in the Southern Hemisphere. The municipality is also Earth's 12th largest city proper by population. The city is the capital of the homonymous state of São Paulo, Brazil's most populous and wealthiest state. It exerts strong international influence in commerce, finance, arts and entertainment. The name of the city honors Saint Paul of Tarsus. The city's metropolitan area of Greater São Paulo ranks as the most populous in Brazil, the 11th most populous on Earth, and largest Portuguese-speaking city in the world.  - Paraguay, officially the Republic of Paraguay, is a landlocked country in central South America, bordered by Argentina to the south and southwest, Brazil to the east and northeast, and Bolivia to the northwest. Paraguay lies on both banks of the Paraguay River, which runs through the center of the country from north to south. Due to its central location in South America, it is sometimes referred to as "Corazón de Sudamérica" ("Heart of South America"). Paraguay is one of the two landlocked countries (the other is Bolivia) that lie outside Afro-Eurasia. Paraguay is the smallest landlocked country in the Americas.  - Latin America is a group of countries and dependencies in the Americas where Romance languages are predominant. The term originated in 19th century France as "Amérique latine" to consider French-speaking territories in the Americas (Haiti, French Guiana, Martinique, Guadeloupe, Saint Martin, Saint Barthélemy) along with the larger group of countries where Spanish and Portuguese languages prevailed. It is therefore broader than the terms Ibero-America or Hispanic Americathough it usually excludes French Canada and modern French Louisiana.  - Goiás is a state of Brazil, located in the Center-West region of the country. The name Goiás (formerly, Goyaz) comes from the name of an indigenous community. The original word seems to have been guaiá, a compound of "gua e iá", meaning "the same person" or "people of the same origin." It borders the Federal District and the states of (from north clockwise) Tocantins, Bahia, Minas Gerais, Mato Grosso do Sul and Mato Grosso.  The most populous state of its region, Goiás is characterized by a landscape of "chapadões" (plateaus). In the height of the drought season, from June to September, the lack of rain makes the level of the Araguaia River go down and exposes almost of beaches, making it the main attraction of the State. At the Emas National Park in the municipality of Mineiros, it is possible to observe the typical fauna and flora from the region. At the Chapada dos Veadeiros the attractions are the canyons, valleys, rapids and waterfalls. Other attractions are the historical city of Goiás (or Old Goiás), from Goiânia, established in the beginning of 18th Century, and Caldas Novas, with its hot water wells attracting more than one million tourists per year. In Brazil's geoeconomic division, Goiás belongs to the Centro-Sul (Center-South), being the northernmost state of the southern portion of Brazil.  - The Cerrado is a vast tropical savanna ecoregion of Brazil, particularly in the states of Goiás, Mato Grosso do Sul, Mato Grosso, Tocantins and Minas Gerais. The Cerrado biome core areas are the plateaus in the center of Brazil. The main habitat types of the Cerrado include: forest savanna, wooded savanna, park savanna and gramineous-woody savanna. Savanna wetlands and gallery forests are also included. The second largest of Brazil's major habitat types, after the Amazonian rainforest, the Cerrado accounts for a full 21 percent of the country's land area (extending marginally into Paraguay and Bolivia).  - Anadenanthera peregrina var. falcata is a timber tree native to Paraguay and Cerrado vegetation in Brazil , specially in Mato Grosso , Mato Grosso do Sul , Minas Gerais , and São Paulo . This plant is also used as an ornamental and medicinal plant .  - Afro-Eurasia, Afroeurasia, or Eurafrasia, is the combination of Africa and Eurasia (Europe and Asia) which together form the largest contiguous landmass on Earth. The term is a portmanteau of the names of its constituent parts.  - The megadiverse countries are a group of countries that harbor the majority of Earth's species and high numbers of endemic species. Conservation International identified 17 megadiverse countries in 1998. Many of them are located in, or partially in, tropical or subtropical regions.  - 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.    After reading the paragraphs above, we are interested in knowing the entity with which 'anadenanthera peregrina var. falcata' exhibits the relationship of 'taxon rank'.
