More information on the many plants and animals found in the different biomes of the world will be added every year as the project grows.

This site was created to teach students the power of the Internet as a tool for both communication and learning,Īnd how to use this tool while at the same time express their scientific/environmental knowledge in a fun way. This website originally evolved from a biome project in Karl Nelson's 6th grade science class at the West Tisbury School, West Tisbury, Massachusetts. The atmosphere, however, could not exist if Earth were not at the exact distance it is from the sun. The atmosphere also screens out lethal levels of the sun's ultraviolet radiation. Earth's thin layer of atmosphere provides all of these elements. Living things also need nitrogen, oxygen, and carbon dioxide. Seventyone percent of its surface is covered by water. Most organisms - both plants and animals - must also have water to live. At night the atmosphere prevents most of the radiant heat from escaping back into space, keeping the surface warm. Radiant energy is filtered by the atmosphere during the day, preventing the surface from overheating. The atmosphere moderates day time and night time temperature swings. These organisms can live on Earth because it has an atmosphere. Animals and plants live almost everywhere on the surface of Earth. The planet is only a tiny part of the universe, but it is the home of human beings and many other organisms. It is the only planet in our solar system that has the components necessary to support life as we recognize it. World Biomes Map – Colouring in: Awesome activity for kids.Earth is truly a remarkable planet. Thus, conservation and preservation of biomes should be a major concern to all. More recently, human activities have drastically altered these communities. Biomes have changed and moved many times during the history of life on Earth. The importance of biomes cannot be overestimated. Mountain grasslands and shrub land biomes are not confined to particular latitudes.
On either side of the equator there are tropical dry forests and rain forests. Where climates are a little moister, subtropical deserts merge into savanna grassland. Deserts vary according to their locations, with some found along western coasts and some in the interiors of continents. A belt of subtropical deserts lies across both hemispheres. In a few parts of the world there is a biome typical of Mediterranean climates, dominated by dry woodlands and chaparral shrub lands. Temperate grassland, the prairies, steppes, pampas and veld, replace the temperature deciduous forest. This biome is restricted to the continental regions with moist climates, while temperate rain forest is found only in the wettest regions.Īs climates grow hotter and drier, the biome changes again. The biome changes and temperate deciduous forest becomes more widespread. Closer to the equator, deciduous trees become more common among the conifers of the boreal forest. Tundra and boreal forest are mainly confined to the Northern Hemisphere, because there is little land at the correct latitude in the Southern Hemisphere. Along its edges, tundra gives way to boreal forest or taiga. Bordering the polar ice is the tundra biome, where the ground is exposed and the temperature rises above freezing for a short time in summer. The climate is exceedingly harsh and there is neither soil nor liquid water at the surface. The range of plants in each biome makes it possible to draw the boundaries in different ways.Īround the poles, the polar ice biome supports no plant life. Other biomes are more difficult to define precisely, because not all plant communities have clear boundaries. Temperate biomes can be found in temperate regions, and polar biomes are located near the poles. Tropical biomes occur between the tropics of Cancer (north) and Capricorn (south). Although general vegetation types can identify biomes, the vegetation in any biome is in fact quite varied because of a number of local differences in land use and environment. The character of this forest is essentially the same throughout the biome, but the plant and animals species found there vary. For example, the belt of mainly evergreen coniferous forests that runs across Canada and northern Eurasia constitutes a biome known as boreal forest in North America and taiga in Russia. These places, occupying large areas and identified by their vegetation types, are known as biomes. Because climate and soil determine which plants thrive in a particular region, similar types of vegetation, as well as the animals associated with them, occur in places with climates that are similar. Biogeography is the scientific study of the way plants and animals are distributed across the globe.
