<–2/”>a >Biome
The terrestrial part of the Biosphere is divisible into enormous regions called biomes, which are characterized, by Climate, vegetation, animal life and general Soil type.
No two biomes are alike.
The most important climatic factors are temperature and Precipitation.
- Tundra– Northern most region adjoining the ice bound poles. Devoid of trees except stunted shrubs in the southern part of tundra biome, ground Flora includes lichen, mosses and sedges.
The typical animals are reindeer, arctic fox polar bear, snowy owl, lemming, arctic hare, ptarmigan. Reptiles and amphibians are almost absent
- Taiga- Northern Europe, Asia and North America. Moderate temperature than tundra. Also known as boreal forest.
The dominating vegetation is coniferous evergreen mostly spruce, with some pine and firs. The Fauna consists of small seed eating birds, hawks, fur bearing carnivores, little mink, elks, puma, Siberian tiger, wolverine, wolves etc.
- Temperate Deciduous Forest- Extends over Central and Southern Europe, Eastern North America, Western China, Japan, New Zealand etc.
Moderate Average temperature and abundant rainfall. These are generally the most productive agricultural areas of the earth The flora includes trees like beech, oak, maple and cherry. Most animals are the familiar vertebrates and invertebrates.
- Tropical rain forest- Tropical areas in the equatorial regions, which is a bound with life. Temperature and rainfall high.
Tropical rainforest covers about 7% of the earth’s surface & 40% of the world’s plant and animal species.
Multiple storey of broad-leafed evergreen tree species are in abundance.
Most animals and epiphytic Plants(An epiphyte is a plant that grows harmlessly upon another plant) are concentrated in the canopy or tree top zones
- Savannah- Tropical region: Savannah is most extensive in Africa
Grasses with scattered trees and fire resisting thorny shrubs.
The fauna include a great diversity of grazers and browsers such as antelopes, buffaloes, zebras, elephants and rhinoceros; the carnivores include lion, cheetah, hyena; and mongoose, and many rodents
- Grassland– North America, Ukraine, etc . Dominated by grasses. Temperate conditions with rather low rainfall. Grasses dominate the vegetation. The fauna include large herbivores like bison, antelope, cattle, rodents, prairie dog, wolves, and a rich and diverse array of ground nesting bird
- Desert- Continental interiors with very low and sporadic rainfall with low humidity. The days are very hot but nights are cold. The flora is drought resistance vegetation such as cactus, euphorbias, sagebrush. Fauna : Reptiles, Mammals and birds.

Biomes are large areas of land or water that have similar climates and plant and animal life. There are many different types of biomes, each with its own unique characteristics.
Aquatic Biomes
Aquatic biomes are biomes that are found in water. There are two main types of aquatic biomes: marine biomes and freshwater biomes. Marine biomes are found in the ocean, while freshwater biomes are found in lakes, rivers, and streams.
Marine Biomes
Marine biomes are the largest type of biome, covering over 70% of the Earth’s surface. Marine biomes are home to a wide variety of plants and animals, including fish, coral, and algae. The open ocean is the largest marine biome, and it is home to a variety of plankton, fish, and whales. The coastal ocean is a transition zone between the open ocean and the land, and it is home to a variety of plants and animals, including seagrasses, MANGROVES, and coral reefs. Estuaries are where rivers meet the ocean, and they are home to a variety of fish, shellfish, and birds. Coral reefs are found in tropical waters, and they are home to a variety of fish, coral, and other invertebrates.
Freshwater Biomes
Freshwater biomes are found in lakes, rivers, and streams. Freshwater biomes are home to a wide variety of plants and animals, including fish, frogs, and turtles. Lakes are large bodies of water that are surrounded by land. Rivers are bodies of water that flow from one place to another. Streams are small bodies of water that flow from a higher elevation to a lower elevation.
Terrestrial Biomes
Terrestrial biomes are biomes that are found on land. There are many different types of terrestrial biomes, each with its own unique characteristics. Some of the most common terrestrial biomes include deserts, grasslands, forests, and tundra.
Deserts
Deserts are dry, hot biomes that receive very little rainfall. Plants and animals that live in deserts have adapted to the dry conditions by developing thick, waxy leaves or by storing water in their bodies. Deserts can be found in many different parts of the world, including North America, South America, Africa, Asia, and Australia.
Grasslands
Grasslands are biomes that are dominated by grasses. Grasslands can be found in many different parts of the world, including North America, South America, Africa, Asia, and Australia. Grasslands are home to a variety of plants and animals, including bison, prairie dogs, and coyotes.
Forests
Forests are biomes that are dominated by trees. Forests can be found in many different parts of the world, including North America, South America, Africa, Asia, and Europe. There are many different types of forests, including temperate forests, tropical forests, and boreal forests.
Temperate Forests
Temperate forests are found in areas with moderate climates. Temperate forests are home to a variety of plants and animals, including trees, birds, and mammals.
Tropical Forests
Tropical forests are found in areas with warm, humid climates. Tropical forests are home to a variety of plants and animals, including trees, birds, and mammals.
Boreal Forests
Boreal forests are found in areas with cold, dry climates. Boreal forests are home to a variety of plants and animals, including trees, birds, and mammals.
Tundra
Tundra is a biome that is found in the Arctic and Antarctic. Tundra is a cold, dry biome that is covered in snow and ice for most of the year. Plants and animals that live in the tundra have adapted to the cold conditions by developing thick fur or feathers.
Mountains are biomes that are found at high altitudes. Mountains can be found in many different parts of the world, including North America, South America, Africa, Asia, and Europe. The climate in mountains varies depending on the altitude. The higher the altitude, the colder the climate.
Biomes are important because they provide habitats for a variety of plants and animals. Biomes also play a role in the Earth’s climate. For example, forests help to regulate the Earth’s temperature by absorbing carbon dioxide from the Atmosphere.
What is a biome?
A biome is a large region of Earth that contains a particular type of climate and certain types of plants and animals.
What are the different types of biomes?
There are many different types of biomes, but some of the most common include:
- Forests: Forests are biomes that are characterized by a high density of trees.
- Grasslands: Grasslands are biomes that are characterized by a high density of grasses.
- Deserts: Deserts are biomes that are characterized by low rainfall and high temperatures.
- Tundra: Tundra is a biome that is characterized by low temperatures and permafrost.
- Taiga: Taiga is a biome that is characterized by coniferous forests.
- Savannas: Savannas are biomes that are characterized by a mix of grasses and trees.
- Chaparral: Chaparral is a biome that is characterized by dense shrubs and small trees.
- Wetlands: Wetlands are biomes that are characterized by a high water table.
What are the characteristics of each biome?
The characteristics of each biome vary depending on the climate and the types of plants and animals that live there. For example, forests are typically characterized by high rainfall, warm temperatures, and a variety of trees. Grasslands are typically characterized by low rainfall, warm temperatures, and a variety of grasses. Deserts are typically characterized by low rainfall, high temperatures, and a variety of desert plants. Tundra is typically characterized by low temperatures, permafrost, and a variety of tundra plants. Taiga is typically characterized by coniferous forests, low temperatures, and permafrost. Savannas are typically characterized by a mix of grasses and trees, warm temperatures, and a variety of savanna plants and animals. Chaparral is typically characterized by dense shrubs and small trees, warm temperatures, and a variety of chaparral plants and animals. Wetlands are typically characterized by a high water table, warm temperatures, and a variety of wetland plants and animals.
What are the benefits of biomes?
Biomes provide many benefits to humans and other organisms. For example, forests provide us with Oxygen, clean water, and wood. Grasslands provide us with food, grazing land, and water. Deserts provide us with Minerals, oil, and natural gas. Tundra provides us with oil, natural gas, and minerals. Taiga provides us with wood, paper, and oil. Savannas provide us with food, grazing land, and water. Chaparral provides us with wood, paper, and oil. Wetlands provide us with flood control, water purification, and fish and wildlife habitat.
What are the threats to biomes?
Biomes are threatened by a variety of factors, including habitat loss, Climate Change, pollution, and invasive species. Habitat loss is the most significant threat to biomes. When forests are cleared for agriculture or development, the animals that live in the forest lose their homes. Climate change is also a major threat to biomes. As the Earth’s climate changes, some biomes are becoming too hot or too cold for the plants and animals that live there. Pollution is another threat to biomes. Air Pollution, Water Pollution, and Soil Pollution can all damage the plants and animals that live in a biome. Invasive species are also a threat to biomes. Invasive species are plants or animals that are not native to a particular biome. When an invasive species is introduced to a biome, it can outcompete the native plants and animals, leading to the decline of the native species.
What can we do to protect biomes?
There are many things we can do to protect biomes. We can reduce our impact on the Environment by conserving energy, recycling, and reducing pollution. We can also support organizations that are working to protect biomes. We can also educate others about the importance of biomes and the threats they face.
