Rice

Domesticated rice Poaceae ("true grass") family, Oryza sativa and Oryza glaberrima. These plants are native to humid and subtropical southern Asia and southeastern Africa. Rice provides more than one fifth of the calories consumed global by humans.(The term "wild rice" can refer to the wild species of Oryza, but predictably refers to species of the related genus Zizania, both wild and domesticated.) Rice is grown as a monocarpic annual plant, although in tropical areas it can endure as a perpetual and can produce a ratoon crop. Rice can grow to 1–1.8 m tall, intermittently more depending on the variety and soil fecundity. The grass has long, slender leaves 50–100 cm long and 2–2.5 cm broad. The small wind-pollinated flowers are shaped in a branched arching to pendulous inflorescence 30–50 cm long. The seed is a particle (caryopsis) 5–12 mm long and 2–3 mm thick.

Rice is a fasten for a large part of the world's human populace, especially in East, South and Southeast Asia, making it the most consumed cereal grain. Rice cultivation is well-suited to countries and regions with low labour costs and high precipitation, as it is very labour-intensive to develop and requires plenty of water for cultivation.

Rice can be grown virtually anywhere, even on steep hillsides. Although its species are native to South Asia and certain parts of Africa, centuries of trade and exportation have made it humdrum in many cultures.

The conventional method for cultivating rice is flooding the fields with or after setting the young seedlings. This simple method requires sound planning and servicing of the water damming and channeling, but reduces the growth of lesser strong tidy and pest plants and reduces vermin that has no submerged growth state. However, with rice growing and agriculture the flooding is not mandatory, whereas all other methods of irrigation require higher effort in weed and pest control during growth periods and a different draw near for fertilizing the mud.

Tiger

The tiger (Panthera tigris) is a creature of the Felidae family, the largest of four "big cats" in the Panthera genus. Native to much of eastern and southern Asia, the tiger is an apex marauder and an necessitate carnivore. Reaching up to 4 metres (13 feet) in total length and weighing up to 300 kg (660 pounds), tigers are equivalent in size to the biggest vanished felids. Aside from their great bulk and power, their most recognizable feature is the pattern of dark vertical stripes that overlays near-white to reddish-orange fur, with lighter underparts.

Highly adjustable, tigers range from the Siberian taiga to open grasslands to tropical mangrove swamps. They are defensive and generally solitary animals, often requiring large adjacent areas of habitat that support their prey demands. This, coupled with the fact that they are prevalent to some of the more densely populated places on earth, has caused significant conflicts with humans. Of the nine subspecies of modern tiger, three are destroyed and the remaining are classified as endangered, some critically so. The primary direct causes are habitat destruction and disintegration and hunting. Their historical range, which once reached from Mesopotamia and the Caucasus through most of South and East Asia, has been radically reduced. While all surviving species are under formal protection, poaching, habitat destruction and inbreeding depression continue to be threats.

Nonetheless, tigers are among most decipherable and popular of the world's charismatic megafauna. They have featured outstandingly in ancient mythology and folklore, and continue to be depicted in modern films and literature. Tigers appear on many flags, coats of arms and as mascots for sporting teams and serve as the national animal of several Asian nations.
