levels all are variables that lead to different results in this experiments. Bacteria can grow in many harsh conditions. One type of classification for bacteria is based on the temperature at which a bacterium can survive. The thermopile bacteria are bacteria that can survive at temperatures of forty-two to one hundred degrees Celsius or more.(Edwards 2) These bacteria are generally found around hot geological sites such as volcanoes and geysers.(Edwards 2) Another class of bacteria are the Acidophiles. Acidophiles are Bacterium that can survive and reproduce within an extremely acidic environment.(Edwards 34) Their environments are highly acidic soils in mining and geothermal areas.(Edwards 34) Oligotrophs are bacteria that can survive on little organic matter such as carbon

(Edwards 93) They are commonly found in ocean water. (Edwards 94) Osmophiles are bacteria that are able to survive in environments with little water.(Edwards 117) Halotolerant and halophilic bacteria are bacteria that can survive with little salt or lots of salt. (Edwards 147) These bacteria are commonly found in salt and soda lakes such as the Great Salt Lake in Utah, the Dead Sea and the soda lakes of the Great Rift Valley in Kenya.(Edwards 149) Metal tolerant bacteria are tolerant to heavy metals that are toxic to microbial life forms.(Edwards 178) All of these different types of bacteria show how they have evolved so that they can live almost every where. Conditions in which bacteria can not live are getting harder and harder to find. Bacteria are thus are highly adaptable

organisms that can live almost any where in the world. They have a seemingly simple but complex structure that is highly organized. Bacteria have different stages of reproduction that is shown in a growth curve that shows the limitations of bacterial reproduction. If bacterial reproduction was not limited the earth would be over run with bacteria.
