What Are Biomes?
Biomes are ecological zones with distinct collections of plants and animals , that have formed because they share the same climate — the same temperature, amount of rainfall and humidity. (3) The biome is the basic unit of the ecological system. It’s the only unit that is small enough to be distinct, but large enough to matter. A biome covers a wider physical area than an ecosystem or habitat: a biome may consist of hundreds of ecosystems, and a great many habitats.
Why Are Biomes Important?
According to conservationists, biomes and other eco-regions are important because they encompass areas with important ecological and evolutionary processes and conditions. Sometimes they contain endangered species of animals or plants whose loss would be irreplaceable. And although tropical rainforests and coral reefs harbor the most biodiversity, unique manifestations of nature can be found in all other biomes, which may be lost forever if they are not safeguarded and conserved. (6)
What are some examples of biomes?
tropical rainforest) may reoccur in several other locations around the world that share a similar climate and other biogeographical conditions. Examples of biomes include: tundra, temperate forests, deserts, and grasslands.
What is the climate of the broadleaf forest?
The climate of the temperate broadleaf forest biome is characterized by plentiful all year-round rainfall (up to 1500mm, 60 inches, annually), along with mild temperatures around 3–16 °C (37–60 °F), at least in the mid-latitudes. The biome has four well-defined seasons, caused by the tilt of the Earth’s axis. During the year, the sun’s rays strike different parts of the world more directly than others, resulting in varying temperatures, or seasons. In the temperate forest biome, this leads to warm summers and cool winters, although conditions vary somewhat around the world. For example, the southern edge of the zone tends to be more humid throughout the year.
How many biospheres are there?

What are the conditions in the tundra biome?
A tundra has extremely inhospitable conditions, with the lowest measured temperatures of any of the five major biomes with average yearly temperatures ranging from -34 to 12 degrees Celsius (-29 to 54 degrees Fahrenheit). They also have a low amount of precipitation, just 15–25 centimeters (six to ten inches) per year, as well as poor quality soil nutrients and short summers. There are two types of tundra: arctic and alpine. The tundra does not have much biodiversity and vegetation is simple, including shrubs, grasses, mosses, and lichens. This is partly due to a frozen layer under the soil surface, called permafrost. The arctic tundra is found north of boreal forests and the alpine tundra is found on mountains where the altitude is too high for trees to survive. Any wildlife inhabiting the tundra must be adapted to its extreme conditions to survive.
What are the two types of grasslands?
Grasslands are open regions that are dominated by grass and have a warm, dry climate. There are two types of grasslands: tropical grasslands (sometimes called savannas) and temperate grasslands . Savannas are found closer to the equator and can have a few scattered trees. They cover almost half of the continent of Africa, as well as areas of Australia, India, and South America. Temperate grasslands are found further away from the equator, in South Africa, Hungary, Argentina, Uruguay, North America, and Russia. They do not have any trees or shrubs, and receive less precipitation than savannas. Prairies and steppes are two types of temperate grasslands; prairies are characterized as having taller grasses, while steppes have shorter grasses.
What is the land covered by evergreen trees called?
land covered by evergreen trees in cool, northern latitudes. Also called taiga.
What are the characteristics of a desert?
Deserts can be either cold or hot, although most of them are found in subtropical areas. Because of their extreme conditions, there is not as much biodiversity found in deserts as in other biomes. Any vegetation and wildlife living in a desert must have special adaptations for surviving in a dry environment. Desert wildlife consists primarily of reptiles and small mammals. Deserts can fall into four categories according to their geographic location or climatic conditions: hot and dry, semiarid, coastal, and cold.

What is the latitude of tropical grasslands?
Tropical grasslands extend on both sides of the equatorial zone upto 25°N latitudes in central and South America, Africa and Australia. In Asia, it extends upto 30° N latitude because of the continental air mass. Alternation of wet and dry seasons results in the growth of a distinctive coarse and tall grass with scattered trees. The areas enjoy hot summers (30°C) and warm winters (20°C). Annual rainfall varies from 25 cm to 100 cm. Soils of the region are mostly similar to those in the equatorial region.
