Oxygen is very important in cellular respiration, without oxygen only anaerobic respiration takes place and this results in two molecules of Adenosine Triphosphate (ATP) which is in basic terms energy. With oxygen 38 molecules of ATP is creating resulting in more energy. Another reason it's not good to not have oxygen present is the build up of Lactic Acid and this weighs the muscle down making it harder to move.

Also understanding the Anaerobic (without oxygen) respiration formula and the Aerobic (with oxygen) formula is important in understanding fatigue of the muscle

Anaerobic Formula
C6H12O6 (Glucose) --> 2 Lactic Acids + 2ATP

Aerobic Formula
C6H12O6 (Glucose) + 6 O2 --> 6 CO2 + 6 H2O + 38 ATP

This happens because the muscle cells respire anaerobically and the glucose is not broken down completely, and Lactic acid is formed. The lactic acid causes pain in the muscles.

Answer:

Larger islands that are large and close to the mainland are shos lower rate of extinction due to the fact that the species present have more space so there will be more resources available in comparison to smaller islands where limited space and limited resources available.

Extinction is greater on islands isolated due to the unlikelihood of immigration and as it is opposite to the island close to the mainland and competition is more in isolated islands.
