Biome Examples

A biome is characterized by a large geographic area with a specific climate, vegetation, and animal life. The biological community of a biome is formed in response to the physical environment and climate of the region. A biome may have several ecosystems and a variety of habitats.


There are mainly five types of biomes: aquatic, grassland, forest, desert, and tundra.

#1. Aquatic Biome

The aquatic biome is further divided into marine and freshwater biomes. The marine biome is the biggest biome on Earth, covering almost three-quarters of Earth’s surface. Examples of marine biomes are oceans, coral reefs, and estuaries. Water bodies having a salt content of less than one percent belong to freshwater biomes, for example, ponds, rivers, and lakes.

#2. Grassland Biome

Grasslands are mostly characterized by a warm, dry climate. Grasslands are further divided into tropical (also called savannas) and temperate grasslands.

Tropical Grasslands (Savannas)

These biomes are found near the equator and cover almost half of the continent of Africa. Savannas are also found in Australia, India, and South America. Savannas are characterized by a few scattered trees.

Temperate Grasslands

Red Valley, South Dakota, a temperate grassland biome

These are found away from the equator and cover areas of South Africa, Hungary, Argentina, Uruguay, North America, and Russia. Temperate grasslands have no trees and shrubs and receive less precipitation than savannas. Temperate grasslands have two types – Prairies, and steppes. Prairies have taller grasses, while steppes have shorter grasses.

#3. Forest Biome

Forests are spread over an area of about one-third of the Earth. Forests are divided into three biomes – temperate forests, tropical forests, and boreal forests (also known as the taiga).

Tropical Forests

These forests are found closer to the equator and have a warm, humid climate.

Temperate Forests

These forests are found at higher latitudes and have all four seasons.

Boreal Forests

These forests are found at even higher latitudes and have the coldest and driest climate. These forests experience precipitation mostly in the form of snow.

#4. Desert Biome

Desert areas cover almost 20 percent of Earth’s surface and are characterized by less than 50 centimeters (20 inches) of rainfall per year.

The biodiversity is very low in these areas, and the vegetation and wildlife have a special adaptation to survive the extreme climatic conditions of deserts. Based on geographic location or climatic conditions, deserts are divided into four categories – hot and dry, semiarid, coastal, and cold.

#5. Tundra Biome

Tundra biomes cover the coldest regions on Earth’s surface. Annual average temperatures of these regions range from -34 to 12 degrees Celsius (-29 to 54 degrees Fahrenheit). These regions are characterized by low annual precipitation (15–25 centimeters), poor-quality soil nutrients, and short summers.

Tundra biomes have very low biodiversity with simple vegetation including shrubs, grasses, mosses, and lichens. Tundra biomes are categorized into two types – arctic, and alpine.

Arctic Tundra

These are found north of boreal forests.

Alpine Tundra

These are found at high altitudes like mountains, where it is hard for trees to survive.
