WHAT ARE THE CHARACTERISTICS OG METHANOGENS,HALOPHILES AND THERMOPHILES
Answers
These are ecological classifications for microbes (each microbe does something special). As each name suggests methanogens ( produce methane, halophiles can live in high salt environments (halo=salt and phile=loving) and thermophiles can live in high temperature environments (thermo=heat and phile=loving).
Methanogens are archaeabacteria (not your typical bacteria, they are actually in a different "family" than bacteria such as E. coli) and are important in the carbon cycle because they can break down organic matter (carbon containing chemicals) and in the process they release methane. The chemical process by which methanogens operate are typically under non-oxygen conditions (anaerobic conditions). Methanogens are also found in cow guts and human guts (and when cows fart, they release methane gas into the air!). Thermophiles and halophiles can be both "regular" bacteria (also called eubacteria) and archaebacteria and both can be classified as "extremophiles" because they love living in extreme environments.
Recall that "old" earth had no oxygen in the atmosphere and since all of these organisms can definitely live without oxygen (in fact methanogens will die in the presence of oxygen), it is reasonable to believe that these organisms could live in the early earth environment. Also recall that the earth was hot back then (perfect for thermophiles) and at some point, was just a big huge sea (great for halophiles) where life was thought to originate. In other words methanogens, thermophiles and, from present sceintific work, halophiles are likely representitives of the first signs of life on eart
