Can you live without bacteria?
Not really no
Archaebacteria called extremeophiles have some species that live entirely anaerobically. Bacteria [and other organisms] that respire using O2 as the 'final' electron acceptor are termed to be Aerobic, while bacteria [and the odd organism] that has the biochemical capacity to Live without O2 are termed to be Anaerobic.
No, one of the qualities of living things is that they need oxygen to live. Yes, there are bacteria and other living organisms that survive without oxygen, living in a methane or other non-oxygenated atmosphere. Bacteria that need oxygen to survive are aerobic. Anaerobic bacteria do not live in an oxygenated atmosphere. In some areas of the deep ocean where there is no oxygen or light there are bacteria that live without oxygen that get…
because the bacterias does not feed on us. But without them we cannot get food, there will not be any decomposition in our surroundings. For example in the matter of foo we can take the example of curd. for making curd, first we need milk but after taking the milk for converting it into curd there must be the micro organism yeast. so we humans cannot live without the bacterias
Let's just put it this way, animals can't live without bacteria. I know that sounds crazy, but there are different kinds of bacteria. The kind that you and I think about a lot are hetatroph bacteria. They cause us to get sick. Autotroph bacteria on the other hand live in you and me inside our intestines. They also live in animals. If we and they didn't have them, we'd die. Hope this helps!
Some bacteria can live with or without oxygen, others can't live with oxygen. Oxygen is used for cellular respiration (breaking down substances, such as sugar, for energy); bacteria that survive without it can ferment organic substances or oxidize inorganic substances. Some animals, such as moss piglets, can enter a state of suspended animation when conditions are bad and survive without food, water, or even oxygen until conditions are favorable again. (Fish can get O2 straight…
