What is biome

For most of the year, the tundra biome is a cold, frozen landscape. This biome has a short growing season, followed by harsh conditions that the plants and animals in the region need special adaptations to survive. Tundra form in two distinct cold and dry regions. Arctic tundra are found on high-latitude landmasses, above the Arctic Circle—in Alaska, Canada, Russia, Greenland, Iceland, and Scandinavia, for example—or on far southern regions, like Antarctica. Alpine tundra are located at very high elevations atop mountains, where overnight temperatures fall below freezing. Tundra regions typically get less than 25 centimeters (10 inches) of precipitation annually, which means these areas are also considered deserts. They have long, cold winters with high winds and average temperatures below freezing for six to ten months of the year. On average, only six to ten weeks of the year have sufficiently warm temperatures and long days for plant growth. The soil in the Arctic is largely permafrost or soil that remains frozen year-round, leaving only a thin surface layer of thawed soil in summer for plant roots to grow in. Tundra soil is also scarce in many of the nutrients that plants need to grow. These conditions lead to one of the tundra biome’s most distinct features: They are largely treeless. (The word “tundra” derives from the Finnish word tunturia, meaning barren or treeless hill.) Instead, the tundra has patchy, low-to-ground vegetation consisting of small shrubs, grasses,...

A vast, northern wilderness–the world’s largest land biome–whose snow-covered landscapes are dominated by dark conifer forests. Welcome to the taiga, an inhospitable region that stretches from coast to coast across North America and Eurasia… Page Index • • • • • • • You can find out more about the taiga biome on these pages: • You can find out more about the animals of the taiga on this page: • Discover the amazing plants of the taiga here: • What is a biome? What are the different types of biomes? Find out on this page: What Is The Taiga? The taiga is a forest biome located in the northern hemisphere. Also known as boreal forest, the taiga lies south of the Arctic tundra and north of the northern temperate forests. Covering around 11.5% of the Earth’s entire land area–that’s roughly 17 million sq. km / 6.6 million sq. miles–the taiga is Earth’s largest land biome. Winters in the taiga are long and cold, and for much of the year the trees and exposed ground of the region are covered in snow. In the summer the taiga explodes with life as plants and animals make use of the short growing season. The taiga is not as biodiverse as the temperate forest biome that lies to its south. Its landscape is dominated by just three main types of tree: spruces, larches and pines. These hardy conifers are better adapted to life in the cold north than broadleaved trees. For much of the year, snow covers the taiga. The above photo shows taiga in Siberia. Animals that live in the taiga include...

• The intertidal zone hugs the shoreline and is greatly affected by tides and waves. • The neritic zone extends to the continental shelf. Enough sunlight penetrates for photosynthesis to take place. Seaweeds are often found here. • The oceanic or pelagic zone extends farther and experiences a mix of temperatures due to current. Large fish and sea mammals ply this zone. • The benthic zone is a deep region beyond the continental shelf. Here sea stars, fish and sponges line the ocean floor. • The abyssal zone represents the deepest ocean zone. High pressure, cold temperatures and essentially no sunlight characterize this zone. J.

For example, the A biota is the total collection of organisms of a geographic region or a time period, from local geographic scales and instantaneous temporal scales all the way up to whole-planet and whole-timescale spatiotemporal scales. The biotas of the Earth make up the Etymology [ ] The term was suggested in 1916 by However, in some contexts, the term biome is used in a different manner.

A biome is a large geographical region characterized by a specific set of environmental conditions, such as climate, soil type, topography, and vegetation. Biomes are categorized based on their climate, which is the primary factor that determines the types of organisms that can thrive in the region. Key Points 1. A biome is a large geographical region with specific environmental conditions like climate, soil type, topography, and vegetation that categorize based on their climate. 2. Each biome has its unique climate, which determines the types of organisms that can survive there. 3. Examples of biomes include tropical rainforests, deserts, tundra, grasslands, taiga, temperate deciduous forests, savannas, wetlands, coral reefs, estuaries, and polar ice caps. 4. There are different types of biomes such as tundra, taiga, desert, freshwater, tropical rainforest, grassland, and savanna, each with unique features and characteristics. 5. Pakistan has several biomes, including the Himalayan mountain range, the Indus River Delta, and the Thar Desert, which include the desert, mountain, and coastal biomes. 6. Biomes refer to large, geographically distinct regions with similar environmental conditions, while ecosystems are smaller, self-contained communities of organisms that interact with each other and their environment.
