Biomes of The World
Desert
A desert is a landscape where little precipitation occurs and, consequently, living conditions create unique biomes and ecosystems.
The lack of vegetation exposes the unprotected surface of the ground to denudation. About one-third of the land surface of the Earth is arid or semi-arid.
-
Savanna
savanna, vegetation type that grows under hot,
seasonally dry climatic conditions and is characterized by an open tree canopy (i.e., scattered trees) above a continuous tall grass understory (the vegetation layer between the forest canopy and the ground).
-
Tundra
Tundra comes from the Finnish word tunturi, meaning treeless plain. It is noted for its frost-molded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons.
Dead organic material functions as a nutrient pool. The two major nutrients are nitrogen and phosphorus.
-
Temperate Forest
A temperate forest is a forest found between the tropical and boreal regions, located in the temperate zone.
It is the second largest biome on our planet, covering 25% of the world's forest area, only behind the boreal forest, which covers about 33%.
-
Tropical Rainforest
The tropical rainforest is a hot, moist biome where it rains all year long. It is known for its dense canopies of vegetation that form three different layers.
