✓ Tropical Rainforest
The Tropical Rain Forest, also known with as jungle or rainforest, is the most complex biome of the world. It is located in low-lying areas of the tropics, typically warm and humid. Through the world, we can identify two types of rain forests: the tropical rainforest and the temperate rainforest.
The biome of the mountain is highly variable with regard to the formation of mountains between each other. Every mountain can have its own species of plants, animals and unique climate. However, height distinguishes the biome of mountains from other biomes. Mountains are relief formations that reach higher altitude in comparison with their surroundings. With increasing elevation, deciduous forests dwindle giving way to coniferous trees which have good development and growth in the cold conditions of the higher elevations.
✓ Temperate Forest
Temperate forests exist in places with variable climate, where the four seasons of the year are well defined. There are three types of temperate forests: the temperate deciduous forest, the evergreen temperate forest, and the mixed temperate forest.
The Boreal Forest is located in the Northern Hemisphere between the latitudes 50º and 60º N, where winters are long and cold. The National Forest is at times called North Coniferous Forest, Taiga.
The polar biome is located in the two poles of the globe: the Arctic (66º 33′ North Latitude) and the Antarctic, on the same latitude, but in the Southern Hemisphere.
✓ Life of Antarctica
The South Polar Region comprises a whole continent, known as Antarctica. The flora in the Antarctic is reduced to lichens and mosses. The lichens form on the bare surfaces of rocks. They are very resistant to cold and drought, and obtain water from the snow and nutrients from the bird droppings. However, there are two flowering species of native plants: the Antarctic Pilosa herb or Antarctic hair grass (Deschampsia antarctica) and the Antarctic pearl or Antarctic pearlwort Colobanthus quitensis). The fauna is represented by mammals such as whales and seals. Still, the groups of the most abundant birds in this region are the marine: the Antarctic petrel, the emperor penguin and Adélie penguins. These three species of birds have adapted to reproduce regularly, unlike other species.
The tundra has a geographical circumpolar location in the Northern Hemisphere. On the other hand, in the Southern Hemisphere it is only found in the Antarctic Peninsula and nearby islands. Cool summers and very cold winters characterize the area of the tundra. Also, it is identified by the presence of a layer of earth that remains constantly frozen, known as the “permafrost”.
Temperate Grasslands are found in five main areas: in the Great Plains of North America, in the pampas of Argentina, in South Africa, in the steppes of Central Eurasia and those around the deserts in Australia. Grasslands are generally located in the center of the continents, where rainfall is intermediate between that of the deserts and forests, and where there are large seasonal variations in temperature and precipitation (hot summers and cold winters/dry winters and wet summers). The presence of trees has been reduced in this area due to the fires, grazing and browsing by herbivores like bison, deer and horses, as well as by the relatively low precipitation. The majority of the prairies have been altered considerably and now they are the main regions of global production of cereals such as wheat, corn and other grains.
✓ Tropical Savannah
The tropical savanna (grassland with scattered trees or groves) is found in warm regions with annual rainfall between 120 and 180 cm. However, there is record of at least one or two long seasons of drought as a result of the fires which significantly affect the environment.
