No, not all forms of life on Earth require oxygen in their environment. There are forms of life, called anaerobic forms, that do not require oxygen. These animals belong to the phylum Loricifera.

∙ 13y agobcz they used their food anerobically ( i.e without free oxygen)
using the food means respiration ( i.e to breakdown food and get energy)
anaerobic breakdown is not complete means the end products r not CO2 and water instead its lactic acid.

∙ 14y agoThere had to be oxygen on the first cells because humans are made out of cells and need oxygen to live. Plants also give of oxygen .
Wiki User
∙ 13y agoNo, because some cells don't use energy so they use oxygen as a replacement
Wiki User
∙ 10y agoNo. Early life forms do not need oxygen to survive.
Wiki User
∙ 10y agoYes. But that's not the only essential element. We actually need almost every stable element in the Periodic Table; there are trace requirements for life for most of them.

Where does the aerobic process of cellular respiration take place?
Aerobic respiration is an almost universal process - carried out by most animals and plants.It consists of several stages, the first of which is shared with anaerobic respiration and takes place in the cytoplasm of cells. The purely aerobic reactions take place inside mitochondria, small specialized organelles within the cytoplasm of all body cells. More active cells have more mitochondria.
List and explain the two types of cellular respiration?
the two main types of cellular respiration are aerobic cellular respiration and anaerobic cellular respiration.
What are disadvantages of fermentation when compared to the processes aerobic and anaerobic respiration?
The equation for anaerobic respiration is: glucose ---> lactic acid + carbon dioxide + energy To know the disadvantages of anaerobic respiration it is best to compare it to aerobic respiration which involves oxygen (glucose + oxygen ---> carbon dioxide + water + energy) For humans to respire regularly and for long periods of time, oxygen is required. This means that anaerobic respiration through humans causes a lack of oxygen, and cannot be carried out for a very long time. Lactic acid is also produce and this is toxic and causes things such as cramp to build up. Anaerobic respiration also produces very little energy compared to aerobic respiration so is not suitable for every day respiration! Humans will mostly breathe anaerobically in situations such as sprinting in a race.
What is the first stage of cell respiration?
energy is captured form sunlight glycolysis
What are three major scientific inferences about the first living cells on earth?
photosynthesis, chemosynthesis, and aerobic respiration1. Little or no oxygen was present on early Earth; 2. Oldest fossils are thought to be cells of living prokaryotes 3. the first cells might have developed in an enviorment filled wit molecules for food
Would the first organisms be aerobic or anaerobic?
Yes. From our lectures, it was discussed that the first true cells were protozoans that lives anaerobically. Oxygen is literally a poison to them.
Did aerobic repsiration evolve before anaerobic respiration?
Aerobic means with oxygen Anaerobic means without. So, anaerobic would have to come first.
Which came first anaerobic or aerobic?
Anaerobic came first, because there was no oxygen in the Earth's original atmosphere.
Is the first step aerobic respiration the first step in anaerobic respiration?
Yes
Would a marathon runner be aerobic or anaerobic?
Technically everyone is both. The first 5 minutes or so are considered anaerobic and then after that the body switches to aerobic metabolism for the remainder of the race.
How are glycolysis and cellar respiration related?
It is the first step. It is common to aerobic and anaerobic respiration
Is a Cyanobacteria a aerobic or a anaerobic?
Cyanobacteria do not require oxygen. They are believed to have produced the first oxygen supply in the Earth's atmosphere, through the process of photosynthesis.

What do you understand by gly colysis?
Glycolysis is the metabolic pathway that breaks down glucose into pyruvate, generating adenosine triphosphate (ATP) and NADH. It occurs in the cytoplasm of cells and is the first step in both aerobic and anaerobic cellular respiration.
What is anaerobic and anaerobic respiration?
Aerobic cellular respiration occurs in the presence of oxygen and anaerobic cellular respiration occurs in the absence of oxygen. Without the presence of oxygen, cellular respiration cannot go past Glycolysis (the first step of cellular respiration) and will be forced to find an alternative route which is, fermentation. Hope this helped.
When does your body need to use anaerobic respiration?
for the first 90 seconds of activity or when you can no longer supply oxygen for aerobic respiration.
Why did anaerobic respiration developed first?
Because aerobic respiration wouldn't have worked very well when there was no oxygen to speak of in the atmosphere.
