Definition of Biosphere

You can describe the biosphere as the total set of all ecosystems that take place on planet Earth and that conform it. The biosphere includes not only all of living beings, if not also to the physical environment in which they inhabit and phenomena that it occur. Defined by many specialists as the space where takes place the life, the biosphere is what makes unique the planet Earth in the solar system since it is until today the only place where the existence of life is known. In addition, the notion of biosphere also includes all relationships that can occur between different living beings and between them and the environment. You may define other terms to the biosphere as the global or planetary ecosystem, can point out that it is percentage distributed between the oceans and the continents, spaces in which different types of ecosystems and habitats (with very particular characteristics) take place. While in the oceans, most of existence happens more or less superficial level, you can also talk of the deep biosphere that is one in which develop certain types of life at the level of the ocean bottom.
These spaces develop the biomes in which certain types of flora and fauna extend. The existing biomes include tundra, taiga, deserts, steppes, the biomes temperate and tropical, among others.
The biosphere is without doubt one of the most complex and engaging natural phenomena that we can witness. Of course, their conditions are not given by chance if not for the existence of various levels of hierarchy that allow that simple forms of life they alternate with more sophisticated forms of organized way. In this sense, the famous Gaia hypothesis holds that biosphere itself maintains adequate conditions for their survival and permanence.
