Microbial ecology is the relationship of microorganisms with one another and with their surroundings. It concerns all three of the major domains of life including Eukaryota, Archaea, and Bacteria. Microorganisms, by their omnipresence, impact the entire biosphere. They are present in virtually all of our planet's environments except the most extreme, from acidic lakes to the deepest ocean, and from frozen environments to hydrothermal vents.
Microbes, especially bacteria, often engage in symbiotic relationships (either positive or negative) with other organisms, and these relationships affect the ecosystem. One example of these fundamental symbioses are chloroplasts, which allow eukaryotes to conduct photosynthesis. Chloroplasts are considered to be endosymbiotic cyanobacteria, a group of bacteria that are thought to be the "inventors" of oxygenic photosynthesis. Some theories state that this invention coincides with a major shift in the early earth's athmosphere, from a reducing atmosphere to an oxygen-rich atmosphere. Some theories go as far as saying that this shift in the balance of gasses might have triggered a global ice-age known as the Snowball Earth.
They are the backbone of all ecosystems, but even more so in the zones where light cannot approach and thus photosynthesis cannot be the basic means to collect energy. In such zones, chemosynthetic microbes provide energy and carbon to the other organisms.
