Biomes of the World
Tundra
The plants tend to be small and close to the ground.
Receives low amounts of precipitation. Less than most of the world's greatest deserts.
Ground have Permafrost.
Found in the regions just below the ice caps of the Arctic, extending across North America, to Europe, and Siberia in Asia.
Animals that live on the tundra must be able to adapt to very cold temperatures.
Savanna
Plants in the savanna have adapted to the long dry season in a number of ways.
Characterized by an extensive cover of grasses with scattered trees.
Associated with climates having seasonal precipitation accompanied with a seasonal drought.
A number of different animal species inhabit the tropical savanna like lions, zebras, elephants and giraffes.
The thorntree and tropical scrub has suffered under the misuse of human activity.
Taiga
All animals have to be well-adapted to the cold.
Alaska, Canada, Scandinavia, and Siberia have taigas. In Russia, the world’s largest taiga stretches
The soil beneath the taiga often contains permafrost
Taiga ecosystems are threatened by direct human activity and climate change.
Taigas are thick forests. Coniferous trees, such as spruce, pine, and fir, are common.
Grassland
Humans have had a dramatic impact on the grassland biome.
Low rainfall, wildland fires, and grazing by animals are three factors that maintain grasslands.
Grassland biomes consist of large open areas of grass. Trees can be present, but they are infrequent.
Temperate grasslands, on the other hand, are known for their rich soil that yields abundant growth of grasses.
The fauna (which do not all occur in the same temperate grassland) include gazelles, zebras, rhinoceroses, wild horses, lions, wolves, prairie dogs, jack rabbits, deer, mice, coyotes, etc.
Forest
Forests are divided en several different habitats.
Dominated by trees and other woody vegetation
Largest and most complex terrestrial biome
Threatened by deforestation for logging, agriculture, and human habitation
Significant role in the global intake of carbon dioxide and production of oxygen
