This biome also occurs around the Mediterranean Sea ( for which it was named ), in southern Australia, along the Pacific Coast of Chile, and at the southernmost tip of South Africa. These five regions are geographically widespread, but they have such similar environmental conditions - poor soils, seasonal rains followed by dry periods, and frequent fires – that the resident plants developed similar adaptations. A total of fourteen terrestrial ( land - based ) biomes have been defined in a system devised by the World Wildlife Fund. This system also delineates ten marine ( oceanic ) biomes and seven in freshwater.
The broadest level of all is the biosphere, which encompasses any part of Earth where life can exist - from the abyssal depths of the ocean to the swirling currents of the atmosphere. It sounds like a huge expanse, but in reality the biosphere is a small space to contain so many living things. Ecologist Barry Commoner once described the biosphere as a" thin, life-supporting skin" around the planet. So far as we know, this is the only place in the solar system capable of supporting life
