What Is A Biome?

A biome is another term for an ecosystem. It is defined as a community of various plants and animals that inhabit a particular type of geographic region of Earth. Biomes are often defined by their climate, rainfall/water characteristics, elevation, and plant characteristics (leaf type, spacing, etc). Biomes can be divided into two major classifications, terrestrial (land-based) and aquatic (water-based). Some major terrestrial biomes include tundra, desert, rain forest, boreal coniferous forest, and temperate deciduous forest. Some major aquatic biomes include lentic freshwater, lotic freshwater, wetlands, open ocean, estuary, and continental shelf water.
Biomes or major communities are the extensive formations of vegetation. The main biomes are: (1) Tundra biome (2) Boreal coniferous forest biomes, (3) Temperate forest biomes, (4) Temperate grassland biomes, (5) Temperate and tropical desert biomes, (6) Tropical rain forest biomes, (7) Tropical deciduous forest biomes, (8) Tropical savanna biomes, (9) wetland biomes and (10) Marine biomes. The temperate grasslands are extensive in the North America and are called as prairies. They are tall grass prairie, mid grass prairie and short grass prairie depending upon the height of the herbage portion.
A biome is a large geographical area characterized by certain types of plants and animals. A biome is defined by the complex interactions of plants and animals with the climate, geology (rock formations), soil types, water resources, and latitude (position north or south on the globe) of an area.
One example of a biome is a desert. Deserts are the world's driest regions. Most of the vegetation there takes the form of drought-resistant plants such as cacti (plural form of cactus), which store water in their stems and have waxy coverings, and scrubby plants like the creosote bush, that have extensive root systems.
The animals that live in the desert are able to survive with little or no water. The camel, for instance, stores water and fat in its hump. And the kangaroo rat gets all the moisture it needs from solid food; it can go its entire life without drinking a drop of water.
Other examples of important biomes include tundra (bitterly cold regions with little plant growth), coniferous (evergreen) forests, deciduous (trees that usually lose their leaves in the fall) forests, grasslands, and tropical rain forests.

Biome is a biological term used in the field of ecology. It is generally defined to be an assemblage or association of plant and animal groups occupying a given geographical location (In Madison we live in the deciduous forest biome). All of the organisms in a biome, plus all of the associated environmental factors with which they interact, are an ecosystem.
Biomes are very large areas on the earth’s surface, with animals and plants adapting to their environment. Biomes are often defined by abiotic factors such as climate, relief, geology, soils and vegetation. A biome is NOT an ecosystem. If you take a closer look, you will notice that different plants or animals in a biome have similar adaptations that make it possible for them to exist in that area. There are many major biomes on earth.
A biome is another word for environment. It is a home to many plants and animals sort of like a community.
A biome is a large geographical area of distinctive plant and animal groups, which are adapted to that particular environment. The climate and geography of a region determines what type of biome can exist in that region.
Biomes are a way to divide the Earth's surface. These divisions are based on climate patterns, soil types, and the animals and plants that inhabit an area. There are biomes on dry land and in water. Every inch of the Earth's surface is a part of one or more biomes.
There are a couple of different ways to look at the number of biomes. Some like to divide biomes into five basic types: aquatic, forest, desert, tundra, and grassland. These five types of biomes can be further divided by differences in seasons or animal and plant species.
The aquatic biome consists of any part of Earth that is covered with water. This includes freshwater and salt water. The aquatic biome can be further divided into freshwater biomes, marine biomes, wetland biomes, coral reef biomes, and estuaries. These subdivisions are based on the salt content of the water, the aquatic plants that live there, and the aquatic animals that thrive there.
The forest biome is the largest and has a wide variety of plants, trees, animals, insects, and microscopic organisms. The major characteristic of the forest biome is its trees. About 30% of the Earth is considered a part of the forest biome. The forest biome is subdivided by its climate and types of trees present. These subdivisions are: the rainforest biome, temperate biome, chaparral biome, alpine biome, and taiga biome.
The desert biome has one major, distinguishing characteristic, the fact that it has very little vegetation. The climate is rather extreme depending on its location. The deserts of Africa are extremely hot during the winters and warm throughout the rest of the year. There are also cold deserts such as those in Antarctica. These deserts are extremely cold during the winter and cold during the other seasons.
Tundra biomes are the coldest places on Earth. They are similar to a cold desert except they receive less rainfall and contain different animals and plants. Even though the conditions are harsh, the tundra biome does have plant and animal habitats.
The grassland biome is made of rolling hills of various grasses. They receive just enough rain to sustain grass but not enough to grow many trees. There are a few trees that will grow in grasslands but sporadic wildfires keep them under control. There are two types of grassland, the savannas and temperate grasslands.
