Some bacteria need oxygen to survive, while others would find it poisonous.
Bacteria that need oxygen to survive are commonly referred to as aerobic bacteria while bacteria that does not require oxygen are anaerobic. There are also bacteria that are classified as facultative anaerobes, this type of bacteria do not require oxygen to survive but prefer to have it.

No, not all bacteria use oxygen to break down food for energy. Some bacteria are anaerobic and can carry out their metabolic processes without oxygen. These bacteria can use other molecules such as sulfate, nitrate, or carbon dioxide as electron acceptors in their metabolism.
FALSE because not all bacteria use oxygen to respire. Like all organisms, bacteria need a constant supply of energy to carry out their functions. This energy comes from food. The process of breaking down food to release its energy is called respiration. Like many other organism, most bacteria need oxygen to break down their food. But a few kinds of bacteria do not need oxygen for respiration. In Fact, those bacteria die if oxygen is present in their surroundings. For them, oxygen is a poison that kills!

Not all bacteria are aerobes (organisms that require oxygen to survive). There are several species of bacteria that can survive even in the absence of oxygen.
These species derive energy by breaking down organic molecules
Not all true bacteria use oxygen in order to breathe. Some forms of bacteria are anaerobic and can operate without oxygen.
Not all bacteria need oxygen to break down food. Anaerobes break down organic molecules to get energy. One example of an anaerobe is the bacterium, Bacteroides fragilis.
Chemoautotrophic bacteria break down inorganic compounds such as sulfur, ammonia, or iron to obtain energy. These bacteria use chemical reactions instead of sunlight to produce energy through a process called chemosynthesis.
In the absence of oxygen, yeast and bacteria carry out fermentation in which they partially break down glucose to produce energy. This process yields 2 ATP molecules along with byproducts such as ethanol or lactic acid.
Bacteria generate energy through a process called fermentation, which does not require mitochondria. In fermentation, bacteria break down sugars to produce energy in the form of ATP.
Decomposers, like bacteria and fungi, use dissolved oxygen in water to break down organic matter through a process called respiration. This helps them obtain energy for their life processes.
Coccus bacteria obtain energy through various metabolic processes, such as aerobic respiration, where they use oxygen to break down organic molecules like sugars to produce ATP. Some coccus species can also utilize fermentation in anaerobic conditions to generate energy. Overall, coccus bacteria can adapt to different environments and energy sources to sustain their cellular functions.
