The multiple layers of vegetation and the superb constant growing conditions lead to very high NPP. Tropical rainforests have the highest mean net primary production of any terrestrial ecosystem, meaning an acre of rainforest stores more carbon than an acre of any other vegetation type. 6.Patient 23 was able to eliminate ONLY the C. jejuni bacteria and no other types of bacteria by taking an antibiotic.
