Most organisms we find in the fossil record depend on oxygen to survive, but it is not necessary in the actual process of fossilization. In fact, a lack of oxygen would actually improve an organism's chance of being preserved, as it would hold back decay.

How long does it take to form a fossil?
There are many types of fossilization. Some take a surprisingly few number of years, and others occur over periods of millions of years.
What are three factors that could prevent an organism from long ago from ever turning up in a fossil collection today?
Not all organisms are equally protected from destruction after death, have structures which fossilize readily, or live and die in environments conducive to fossilization. Even if fossilization does occur, the fossil is subject to destructive geologic forces such as melting, crushing or erosion. And finally, most fossils remain hidden from us, buried deep inside the Earth.
Do Archaebacteria need oxygen?
No they live in harsh conditions so they won't always be needing oxygen.
What fossilization process involves the transformation of organic material into a thin film of water?
Carbonization
Why does oxygen diffusion from the alveolus to the alveolar capillary occur?
Diffusion (of anything) occurs because of a concentration gradient meaning there is more oxygen in one place than another. Alveolus when you inhale will have a higher concentration of oxygen that that of the alveolar capillary resulting in a concentration gradient, this causing diffusion to occur until equilibrium is met. This means more oxygen in alveolus so oxygen travels into the alveolar capillary until a balanced amount of oxygen is in both places, but then of course the oxygen is transported and you exhale and inhale so the process repeats.
What type of condition must be for minerals fossilization to occur?
what type of conditionals must be present for mineral fossilization to occur
Can mineral fossilization occur without the presence of water?
yes,because as long as the organism is buried,it can become fossilization
What are the different types of fossilization that can occur?
Cast, imprint, amber, and frozen
Can mineral fossilization occur without the precence of water?
it is a frozen beach
What type of conditions must be present for mineral fossilization to occur?
An important factor to make fossil formation more likely is rapid burial or coverage of the object so it isn't exposed to much air. There also needs to be an absence of decomposers.
Are fossils formed?
There are multiple methods of fossilization, but fossils generally are formed by rapid burial of organisms or traces of organisms by sediments. Fossils occur when the organic material is filled with minerals or the cells of an organism is replaced by the minerals in water. Most of the minerals came from rocks and sands. Here are the conditions for fossilization or permineralization: 1. Mineral-rich water like flood water or ground-erupted water. 2. Lack of oxygen - to prevent decomposition by oxygen. 3. Pressure - particularly in woods so that minerals can seep deep inside. 4. Usually occur within a few years - fossilization must occur quickly before decomposition takes place. When a Plant or animal dies in a watery environment and is buried in sediment or soft tissues quickly decomposed leaving the hard bone or shells behind.
Why do blood cells need oxygen?
Blood cells need oxygen to move and reproduce, without it, they would die. And in time, you would also die.
What does a cell need for cell respiration to occur?
aerobic respiration needs oxygen to generate energy, occasionally anaerobic respiration can occur which is when an organism can produce energy without using oxygen. Most cells need oxygen to respire. The simple reaction is: glucose + oxygen = energy + waste products (carbon dioxide + water)
What rocks will you find fossils in?
Sedimentary rocks - things like limestone, sandstone, shale, slate, etc. This is because to get fossilization, you need preservation of the corpse. You need anoxic (no oxygen) conditions (so bacteria do not deteriorate the body), and fast burial (to preserve the body).

What do you need for a burning to occur?
Fuel, Oxygen and a spark to ignite the flame. Use the Fire triangle.
Do all pathogens need oxygen to grow?
no, not all pathogens need oxygen to grow. pathogens that grow without oxygen can occur in cooked rice, untreated garlic and oil mixtures, and temperature-abused baked potatoes.
