Biosphere

The levels of organization in Biology can be arranged in the following order: atom, molecule, organelle, cell, tissue, organ, system, organism, population, community, ecosystem and biosphere.

The watercourse is to the biosphere what blood circulation is to a human being.

The word biosphere comes from a Greek word meaning "life globe."

In this place of beauty, there is an underside of lawlessness, corruption and poverty that could threaten the sustainability of the biosphere.

It is the 25th of March of 2015. Once again, war is on the mind of Lulu Islanders. What really is the current state of weapons technology? Are they great enough to damage the resilience of the biosphere? Or, do enemies want to use biological warfare, to spread a deadly virus of some sort? Common people think of fire when they think of war. However, a big war may not be of fire. Some still hold to the idea of raining hot missiles, a torrent of nuclear bombs. But biological weapons may not destroy valuable real estate. Yes, humans are still fighting primates. Racial intolerance is a sign that people still cannot live in peace. The real hope is that there is the probability of life beyond this Earth. Even if humans were to destroy themselves, there would be life elsewhere, outside of Earth. Such is the real hope.

The system will build on existing global systems to provide near real-time data on changes in the Earth's lands, oceans, atmosphere and biosphere through a single Web portal.

The Permian mass extinction is the largest biosphere catastrophe in Earth's history.

Patavig is the second of the Macedon system's giant terrestrial planets, and by far the more interesting. Most of the surface is covered by a vast sea of liquid ammonia, in which a unique aquatic ammonia-based biosphere has developed. While the frozen continents are largely bereft of life, a rich bounty of complex organisms — many larger than a human — flourish in the chilly, toxic seas.
