      Hallo

      right to explain aerobic first….electrons are passed down from your donor..for us thats usually glucose..which we get from food..this gets passed down a chain of molucules called an electron transport chain..which causes ATP ( chemical enrgy the cells can use) to be rproduced. At the end of the chain we need a molecule to catch and take away the electron…we use oxygen hence we are aerobic..
      bacteria can use nitrate, sulphate methane etc to catch the electron so can grow in mnay areas where there is no oxygen…We can’t

      as for how many hard to say many species do a bit of aerobic…but can use anaerobic if they have to without even starting on feremtation whcih is another topic entirely

      clostridum ( tetani and botulimium for example) are anaerobic and die in oxygen ( so would we if we didn’t have enxymes to protect us..oxygen is quite toxic…weird i know)
