The tropical forest covers most of the land.
For land, it's the taiga, but the marine biome covers 75% of the earth, so...
Tundra
Deciduous Forests
tiaga is made up of coniferous trees and is known as coniferous forest estuary is the biome where fresh water streams and the ocean meet the main difference is that the taiga biome is a land biome and estuary is a water biome
A Savanna biome is a rolling grass land scattered with shrubs and isolated trees, which can be found between a tropical rainforest biome and a desert biome. Not enough rain falls on a Savanna biome to support forests. Savannas are also known as tropical grasslands. They are found in a wide band on either side of the equator on the edges of tropical rainforests. In the Savanna biome it is warm yer rond but there are 2 very different seasons. Winter and Summer. In the winter time they get about 4 inches of rainfall and during December to Febuary there is no rainfall. In Winter time its very dry. In Summer they get lots of rainfall. Its so humid and hot that heat rises up from the ground and mixes with the cool air above then creates rain. The Savanna biome covers about 10% of the earths surface out of all the biomes.
Its maybe the tropical forest... man I don't know the accurate answer.
