They cover every imaginable surface where there is sufficient moisture, and they live on and inside of other living things. In the typical human body, prokaryotic cells outnumber human body cells by about ten to one. They comprise the majority of living things in all ecosystems. Some prokaryotes thrive in environments that are inhospitable for most living things.

The detritus of aquatic ecosystems is organic material that is suspended in the water and accumulates in depositions on the floor of the body of water; when this floor is a seabed, such a deposition is denominated "marine snow".

As rain falls through the atmosphere, sulfur dioxide (SO 2 ) in the atmosphere is dissolved in the form of weak sulfuric acid (H 2 SO 4 ), creating acid rain.

Prokaryotes are well adapted to living in all types of conditions, including extreme ones, and some prefer to live in colonies called biofilms. Archaea are believed to have evolved from gram-positive bacteria and can occupy more extreme environments.

The biosphere extends into the atmosphere (several kilometers above Earth) and into the depths of the oceans. Despite its apparent vastness to an individual human, the biosphere occupies only a minute space when compared to the known universe. Many abiotic forces influence where life can exist and the types of organisms found in the biosphere.

In 2018, the additional flux of carbon into the atmosphere from anthropogenic sources was estimated to be 36.6 gigatons of carbon (GtC = 1 billion tons of carbon)—a significant disturbance to the natural carbon cycle that had been in balance for several thousand years previously.
