Q: Context: An epiphyte is a plant that grows harmlessly upon another plant (such as a tree) and derives its moisture and nutrients from the air, rain, and sometimes from debris accumulating around it. Epiphytes differ from parasites in that epiphytes grow on other plants for physical support and do not necessarily negatively affect the host. An epiphytic organism that is not a plant is called an epibiont. Epiphytes are usually found in the temperate zone (e.g., many mosses, liverworts, lichens, and algae) or in the tropics (e.g., many ferns, cacti, orchids, and bromeliads). Epiphyte species make good houseplants due to their minimal water and soil requirements. Epiphytes provide a rich and diverse habitat for other organisms including animals, fungi, bacteria, and myxomycetes., Bromelioideae is a subfamily of the bromeliads (Bromeliaceae). This subfamily is the most diverse, represented by the greatest number of genera with 32, but the least number of species with 861. Most of the plants in this group are epiphytes, though some have evolved in, or will adapt to, terrestrial conditions. This subfamily features the most plant types which are commonly cultivated by people, including the pineapple., Aechmea blumenavii var. alba is a species in the genus Aechmea . This species is endemic to Brazil ., The Bromeliaceae (the bromeliads) are a family of monocot flowering plants of 51 genera and around 3475 known species native mainly to the tropical Americas, with a few species found in the American subtropics and one in tropical west Africa, "Pitcairnia feliciana"., Aechmea is a genus in the botanical family Bromeliaceae, subfamily Bromelioideae. The name comes from the Greek aichme (a spear). "Aechmea" has 8 subgenera and 255 species distributed from Mexico through South America. Most of the species in this genus are epiphytes., 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., 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., 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., Subject: aechmea blumenavii var. alba, Relation: taxon_rank, Options: (A) family (B) genus (C) group (D) species (E) subfamily (F) variety
