Bacteria

Bacteria
Essentially, there are 3 general types of bacteria, each being specialised to different environments and having specific advantages in various organisms in relation to other forms. They exist all around us, in the air we breathe, on the surfaces we touch, on our skin, and within us. Many bacteria, contrary to popular misconception do not actually do any harm to mankind, and in fact, can be helpful to us, such as the bacteria responsible for turning milk to yogurt, breaking down detritus into soil, and those which live symbiotically in our gut. Typically a few micrometres in length, bacteria have a number of shapes, ranging from spheres to rods and spirals. Bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, acidic hot springs, radioactive waste, and the deep portions of Earth's crust. Bacteria also live in symbiotic and parasitic relationships with plants and animals. They are also known to have flourished in manned spacecraft.

There are typically 40 million bacterial cells in a gram of soil and a million bacterial cells in a millilitre of fresh water. There are approximately 5×10³⁰ bacteria on Earth, forming a biomass which exceeds that of all plants and animals. [ more from wikipedia... ]
