The biosphere is the global sum of all ecosystems. It can also be called the zone of life on Earth‚ a closed (apart from solar and cosmic radiation)‚ and self-regulating system.[1] From the broadest biophysiologicalpoint of view‚ the biosphere is the global ecological system integrating all living beings and their relationships‚ including their interaction with the elements of the lithosphere‚ hydrosphere‚ and atmosphere. The biosphere is postulated to have evolved‚ beginning through a process of biogenesis or biopoesis

TUNDRA CLIMATE The tundra biome is characterized by extremely cold temperatures and treeless‚ frozen landscapes. There are two types of tundra‚ the arctic tundra and the alpine tundra . ARCTIC TUNDRA The arctic tundra is located in the extreme northern hemisphere around the North Pole. This area experiences low amounts of precipitation and extremely cold temperatures for most of the year. The arctic tundra typically receives less than 10 inches of precipitation per year (mostly in the form of

Name: ______________________________ The Tropical Rainforest Rainforest Series‚ Part 1 - by Mikki Sadil Tropical rainforests are among the most mysterious of all geographical biomes in the world. A biome is an area with very distinctive plants and animals that have adapted to life in that particular environment. Rainforests have covered large portions of the Earth for millions of years‚ and can have trees that are 1‚000 years-old or more. They are called rainforests because they are among the

months and summer isn’t much better. Average summer temperatures range from 64 to 72 degrees fahrenheit and taigas usually have only 50 to 100 frost free days. Taigas get around 33 inches of rain annually on average and despite what one may think the biome is actually quite humid. Due to low temperatures evaporation rates are low leaving the area with lots of excess moisture. The taiga (referred to as the Boreal Forest in this picture) is the pale yellow‚ stretching across the top of North America‚

at the library reading about marine organisms‚ their habitats‚ their adaptations‚ and how they interacted with other organisms. In middle school‚ I participated in a project that consisted of decorating the classroom to represent a biome‚ and I worked on the marine biome. In the summer before 10th grade‚ I visited Sea World and was exposed to an even larger variety of marine organisms than I had been before. That fall‚ in English class we had to write a paper on our career goals; I decided I would

precipitation will fall mainly as snow. The soil in the coniferous forest is poor and rocky. This happens because the tree’s roots (especially pines’) are deeply shallow. So the plants in the coniferous forest adapt to survive in these conditions. This biome is similar to tundra and deciduous forest‚ but there are some differences. The differences between the coniferous forest and tundra: In the tundra‚ it is windy like the coniferous forest. In the coniferous forest‚ it rains and snows. In the tundra

Biomes and Diversity Extinction is a natural selection process. Should humans strive to preserve a representative sample of all biomes or aquatic zones? Why should humans be concerned with the extinction rate? This is an interesting question. Lets consider the fact that it begins by stating extinction is a natural selection process. This seems to stifle one side of this argument.The side of the argument that rallies humans to be concerned with the extinction rate and strive to preserve a representation
