aerobes are those which require free molecular oxygen about 21% in air while facultative anaerobes can survive in both conditions presence and absence of oxygen
Aerobic bacteria absorb oxygen from their surroundings and use this to oxidise sugars in order to release energy. Firstly the oxygen is used to remove carbon from the sugars (carboxylation) this releases carbon dioxide. Electrons are removed from the sugar compounds and pass along an electron transport chain in the mesosome membrane. The electrons then combine with oxygen and protons at the end of the chain to form water. This is called aerobic respiration.
Anaerbic bacteria do not do this full process. They partially break down sugars in the absence of oxygen, this anaerobic respiration releases far less energy.
Your body has different systems for producing the energy you need. These systems are either anaerobic -- not using oxygen -- or aerobic -- using oxygen.
Essentially, here's how it works. When you first start exercises you're using stored energy (ATP) and then you start converting sugar into energy (anaerobic glycolysis).
After that your body needs to start producing energy using oxygen, i.e. aerobically.
arrobic grows faster than anaerobic bacteria
The root "aero-" refers to oxygen. Aerobic means in the presence of oxygen. Anaerobic means in the absence of oxygen.
aerobe
A faculatative anerobe does NOT require oxygen for growth but may use if available so it can grow in aerobic and anaerobic conditions. Too much oxygen is NOT toxic. A micro-aerofile CAN'T grow without oxygen but too much oxygen is toxic so it must have a low concentration in order to grow.
It is caused by the bacteria dying, because it ran out of oxygen. The bacteria that formed a pellicle would be considered a oligate aerobe or strict aerobe, because it can only survive in the presence of oxygen.
Obligate aerobes must always have access to oxygen to survive.
answer difference between ontogeny and phylogeny?
Aerobes utilize and thrive in oxygen, anaerobes are killed/ fail to thrive in oxygen.

It is facultatively anaerobic
Prokaryotic cell. Also the first cell according to anerobe heterotroph hypothesis.

No Micrococcus luteus is aerobic organism, Staphylococcus aureus is often mistaken for Micrococcus luteus but its main difference is that it is a Facultative anaerobe
It is neither, since it is not living.
