Explanation:
The reason why these unicellular organisms were able to survive harsh environments was they developed strategies for respiration and survival tactics. As the environment long ago was basically very hot and mostly consisting of methane, the gist of their survival was anaerobic respiration and them being thermophilic bacteria. Thermophilic bacteria are unicellular organisms which can survive extremely hot temperatures. Anaerobic respiration is the process of using energy without using chemical reactions involving oxygen. Later, cyanobacteria produce oxygen as a byproduct in respiration, resulting in the formation of our oxygen-rich atmosphere which allowed new bacteria to evolve.
The organisms present were unicellular, and their names were Amoeba, Cyanobacteria, Diatoms, Paramecium, Euglena, Chlorella, and Yeast.
The processes depend on the time period. 3-4 Billion years ago, the process the organisms were able to carry out was anaerobic cellular respiration as there was no oxygen on the Earth, only methane. Anaerobic respiration also produces energy and uses glucose, but it produces less energy and does not require oxygen. 2-3 Billion years ago, oxygen was used in the following equation for aerobic respiration:
C6 H12 O6 + O2= Energy+CO2+H2O
Glucose + Oxygen= Energy + Carbon di oxide + Water
For Anaerobic Respiration, the nutritional demands were basically this in the equation:
The chemical equation is C6H12O6 = 2C3H6O3 (Glucose = Lactic acid).
Then it also needed it to be oxidized in Carbon di oxide and water, resulting in oxygen debt.
Aerobic respiration only needed glucose and oxygen to produce energy for carrying out life processes.
