Anaerobic respiration.
<span>Anaerobic respiration is a type of cellular respiration BUT does not use oxygen (O2). It is used when there is not enough O2 for aerobic respiration.
</span><span>It can be summarised by the equation: glucose → lactic acid (+ energy released). However, it releases less energy than aerobic repspiration due to a lack of oxygen resulting in an INCOMPLETE breakdown of glucose.

Answer:
See the answer below
Explanation:
<em>Amphibians are not totally adapted to live on land because the aquatic environment is needed for several life processes such as </em><em>reproduction</em><em>, </em><em>respiration</em><em>, and sometimes, </em><em>feeding</em><em>.</em>
<u>The eggs of amphibians are without any protective shells and will suffer desiccation in the terrestrial environment. Hence, water is needed in order to protect the eggs. In addition, the male am</u>phibians shed their sperm in the water close to the female eggs.
<u>The young ones of amphibians are essentially aquatic and may not survive out of water for a long time because they only breathe gills</u> - the lung is yet to develop or poorly developed at this stage. They have to grow and develop to a certain stage in water before they can start surviving on land.
