The Biomes will be defined primarily by factors such as plant structures , leaf types and the spaces between the plants, because the biomes are identified primarily by particular patterns of ecological succession and vegetation. Moreover, the biomes are classified into terrestrial Biomes , Biomes Marine and freshwater , but are mostly known by local names by which they are commonly designated , grasslands, shrublands and sheets , among others. As long as it we mentioned above , the weather is the main decision maker and definer of a biome and especially in determining the distribution of terrestrial biomes , depending on the same the following issues : the latitude to define the types arctic , boreal, tropical, subtropical and temperate ; determine the moisture wet types , semi-wet , arid and semiarid and finally the altitude, which is what defines the montage , montage , alpine and alvar types . Large and major biomes of the world.
Rain forest
The rainforest, also called as tropical rain forest is characterized by its density and tropical climate in which abundant rainfall and the average temperature is usually high Undoubtedly this is the most extensive and important ecosystem of our planet and owns a wealth and variety of the species presented.

Savannah
Meanwhile, Savannah is an ecosystem that is characterized by the presence of trees and shrubs , while the trees produce low coverage because they are rather small and sparse trees. It is characterized by its dry climate being a transition zone between the forest and the semi-desert. Mostly found in the savannas in tropical and subtropical regions that have dry tropical climates.____________________________________________________________________________
The steppe is a biome consisting of flat land with herbaceous vegetation in which extreme weather and low rainfall , which can not exceed 250 mm in the year prevail. The steppes be found far from the seas and as we said, with a huge variation in temperature in both summer and winter. The vegetation is rather low , scrub type . The soil is rich in minerals and low in organic matter.

Temperate Rainforest
The temperate forest biome is the greater diversity of our planet , however, and unfortunately the indiscriminate use of the human being from their trees , for firewood , for building, among others, has led to its decline and in some cases their loss.
Tundra
The tundra extends around the north and south poles , being case its freezing temperatures and frozen ground. Virtually no green trees and the ground may be covered with mosses and lichens It should be noted that there are other similes in the Tundra biomes in the high mountains , as in the case of Tibet
