World biomes

A biome is a large ecosystem: they are parts of the world who share basic characteristics such as climate (seasons, time and temperature). There are many biomes on our planet and there are different ways to tell them apart. The following biomes are general classifications: each of the five largest biomes can be divided into more specific biomes.

The aquatic biome covers all ecosystems in the water. Oceans, lakes, rivers, hot springs, springs, wetlands and other water bodies are aquatic biomes. The aquatic biome is the largest biome. It occupies about 75% of the surface of the Earth. Life developed in the aquatic biome about 3.5 billion years ago. The aquatic biome is divided into two biomes according to the percentage of salt containing water

The forest biome is defined as habitats dominated by trees. Forests cover about one third of the land surface of the Earth. The forest biome is divided into three classifications according to the type of forest: temperate, tropical (forest) and boreal.

Tundra is a habitat characterized by cold weather, permanently frozen soils, long winters and limited drainage. Tundra biome is located near the North and South Poles and in the tops of the highest mountains in the world. It covers about a fifth of the land on the planet. There are three types of tundra

The grassland biome is dominated by grasses, grasses, reeds or grasses and covers large areas of Africa, Australia, America and Asia. Grasslands do not receive enough precipitation to support much vegetation, but are not as dry as deserts. There are two main types of grassland

The desert biome covers all ecosystems receive less than 50 centimeters of precipitation a year. Due to the harsh conditions, the flora and fauna that inhabit the desert ecosystems have special adaptations to survive. The desert biome is divided into four types of deserts
