    Why does ploughing decrease biodiveristy

    • @AlevelBiologyHelp
      @AlevelBiologyHelp 2 ปีที่แล้ว +3

      Because ploughing can release carbon into the atmosphere, so it cannot be assimilated by microorganisms , decreasing biodiversity. :) It can also do obvious things like destro habitats and destroy crops :)

    Hi I wanted to know do you have to memorise the index kfc diversity formula or will that be given in the exam, thanks

      In the past, you've been usually given the formula, but I would recommend memorising it just in case! :)
