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.

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.

What uses oxygen to break down food for energy?

The process of breaking down food for energy using oxygen is called cellular respiration. This process occurs in mitochondria within cells and involves the conversion of glucose and oxygen into ATP, the main energy currency of cells. Through cellular respiration, cells generate energy, carbon dioxide, and water as byproducts.


Is oxygen consumed when aerobic bacteria break down dead algae in a pond?

Yes, oxygen is consumed by the aerobic bacteria in degrading the dead algae. Oxygen is used by bacteria in aerobic respiration. Lots of energy needed for degradation of organic matter in to inorganic comes from cellular respiration of bacterial cells.


What breaks down foos and releases energy?

Bacteria helps you break down food along with your stomach acid. the process of respiration allows you to release energy. Resperation is the process in which food is broken down and energy is released.
