What condition is required for fermentation to occur?

The condition required for fermentation to occur is when the oxygen levels within a cell are too low for aerobic respiration.

Further Explanation:Cellular respirationThis is the process by which food substances such as glucose are broken down to yield energy in the form of ATP for the cells. The energy is then sued to drive cellular activities such as transport and cell division.Cellular respiration is classified into two;Aerobic respiration.Aerobic respiration is a type of respiration that takes place in living organisms in the presence of oxygen gas.The process involves the breakdown of organic compounds such as glucose to yield energy in the form of ATP and carbon dioxide together with water as byproducts.Anaerobic respiration/Fermentation Anaerobic respiration on the other hand is a type of respiration that occurs in absence of oxygen gas or in presence of low levels of oxygen gas in the cells.It involves the breakdown of organic compounds to form small amount of energy in the form of ATP and ethanol or lactic acid as byproducts.Anaerobic respiration/Fermentation occurs in two stages;Glycolysis; One glucose molecule is broken down to pyruvate and two molecules of ATP are formed.Fermentation; This is the second stage of anaerobic respiration, pyruvate from glycolysis can undergo various steps depending on the living organism. It can be converted to ethanol or lactic acid together with carbon dioxide.

An ecosystem is in a certain area and includes living and non living plus there is weather conditions and a biome is a large amount of area with similar climate.so ecosystem is based on weather and biome is based on the average climate
